How to convert real dimensions to scale. The scale. Scale in photography

On any geographic map, you can see approximately the following inscription: "Scale 1: 100,000". Traditionally, the first number is 1, and the second can vary. If there is no inscription, then by all means there is a tiny ruler, divided into equal segments, or a nomogram. These signs indicate the ratio of the size of this or that object on the map or plan to its actual size.

You will need

• Roulette or compasses
• Ruler

Instructions

1. If you have a plan on which different objects are plotted fairly correctly, and you need to find out to what scale this plan was made, start with measurements. Select an object, the one that is nearby. Measure it on the plan and write down the results.

2. Measure the object itself. Use a tape measure for this. In order to avoid mistakes, make a peg and hook the loop of the roulette on it. Drive the peg into the ground so that the zero mark of the tape is on the tier of the starting point of the length or width of the object.

3. Determine the scale. It is more comfortable to write it down in numbers for everyone. Write down the size of the object on the plan, after that - the one that turned out when measured on the territory. Let's say that you found that a 5-meter barn on the plan is 2.5 cm long. Convert meters to centimeters. That is, it turns out that you have 500 cm in 2.5 cm.Calculate how many centimeters of territory are contained in 1 cm on the plan. To do this, divide the larger number by the smaller one. It turns out 2.5: 500 = 1: 200, that is, 1 cm on the plan corresponds to 2 m on the territory.

4. In order to determine the scale more correctly, take several measurements. Let's say measure the barn on the site and the distance from the gate to the pond. Plans are different, and the size of this or that object can be applied unsatisfactorily correctly. If there is a discrepancy, make another froze. Correct the image of the object that does not correspond to the other two on the plan.

Scale is a numerical designation of parameters related to real objects, which are unthinkable to depict in natural size. The figure applies their layouts.

Instructions

1. The scale is written down by several methods, say, numerically - 1: 1,000,000. The size ratio can also be indicated in this form: 1 cm 10 km is a named scale. The linear display method is shown by a ticked line.

2. When considering scale in relation to cartography, the appearance of a particular map will depend on the ratios used. The larger it is, the more detailed the area will be depicted. The detail is also influenced by the nature of the territory, which is sparsely populated, for example, it is easier to depict. Maps come in large, medium and small scale. Large-scale maps are when 1 cm is from 100 to 2000 meters, medium-scale maps are 1 cm to 10 km, small-scale maps are 1 cm more than 10 km.

3. The scale is also significant in photography. With the help of lenses, photographers change sizes from a hefty small to a hefty large. The scale metamorphosis methodology depends on the specifics of the survey. If these are small objects, say, insects, the scale increases, if they are huge, it decreases.

4. The concept is used in many sciences as well. In mathematics it is a ratio of numbers, in programming it is a time scale, in astronomy it is a scale of the universe. The meaning of the word is also used in the construction industry.

5. Firms are distinguished by the scale of their activities. There are, say, territorial organizations, and there are federal organizations. People are also different in scale. True, not from a physical point of view, there is a psychological representation of the "scale of the figure". This means human qualities, goals and performance results.

Note!
The size of the reduced object is relative to its natural size. The distance between objects can be changed by several centimeters, meters, kilometers. The scale of reality changes a lot, but all parameters must remain proportional. If you do not respect the proportions, it will be unthinkable to analyze the distances and sizes of objects.

With the need to imagine the real dimensions of the object depicted in the drawing, a person comes across more closely at school. In a drawing lesson, it may be necessary to draw a detail on a scale of 1: 2 or 1: 4, in a geography lesson, to calculate the exact distance between two cities. In order to cope with the task, you need to know how the scale is translated.

You will need

• - geographic map;
• - detail drawing;
• - calculator;
• - drawing accessories.

Instructions

1. If you need to draw parts on a 1: 1 scale, this means that 1 cm of the surface will correspond to 1 cm in the drawing. Measure the surface that you want to depict and draw it on paper at its natural size.

2. Other scales are used in the drawing. 1: 2 means that the part in the drawing should be half as large as it actually is. If the scale is 1; 4, this means that 1 cm in the drawing is equal to 4 cm of the part. It also happens on the contrary. Any small object can be drawn, say, on a scale of 4: 1, 10: 1, etc. If you see a similar designation in front of you, it means that the object in the picture is four or ten times larger than it actually is.

3. In geography, translation of scale is also required. Look at the geographic map. In one of the lower corners you will see either a ruler with numbers, or primitive numbers - say, 1:50 000. The numbers, finally, are larger than in the drawing, but the rule for translating them is the same, that is, in the example given, 1 cm of the map 50,000 cm of the earth's surface is brought, that is, 500 m. This is a map of a relatively huge scale. Looking at the atlas of the world, you will see much more impressive numbers.

4. Quite often it is necessary to translate the scale of not a linear measure, but a square one, that is, determine how many square centimeters. To do this, measure the area you need using any convenient method. Let's say with palette support. In order to find out the real area of ​​the territory, you need to translate the linear scale into a square, that is, build the number of centimeters contained in 1 cm of the map into a square. Multiply the resulting number by the area of ​​the site shown on the map. Thus, you will find out how many square meters the territory of your concern occupies.

5. Occasionally, it becomes necessary to translate the scale of a volumetric object. For example, in a labor lesson, a teacher can give an assignment to make a detail shown in a technical drawing on a certain scale. You need to find out how much material is required for this. The translation thesis will be the same. First, find out how many real centimeters correspond to this or that line in the drawing. Determine the volume of the part from the drawing. This is a simple math problem, the method for solving it depends on the shape of a particular part. The number that indicates the scale, raise to a cube, and then multiply by the volume of the part, calculated according to the drawing data.

Useful advice
You can try to draw a simple plan yourself by setting a certain scale for yourself. Let's say a 1:10 scale for a room plan is absolutely fine. Measure the length of the walls and large objects, determine their relative position and draw a plan in exact accordance with the data received.

Note!
The smaller the denominator of the fraction with which it is written, the larger the scale. 1: 100 is larger than 1: 2,000. Measuring an object is more comfortable with an assistant. If there is no assistant, and the peg is not at hand, press the tape firmly against the wall of the object. It is more comfortable to measure each on the ground - say, along the bottom of a wall.

The scale of the map, at a given point and in a given direction, is the ratio of the length of the line taken around this point at this direction on the map, to the corresponding length on the ball or ellipsoid.

The scale value remains constant only on the plan and cannot be constant on all parts of the map. However, on maps, as well as on plans, usually a single scale value is placed. This is the main scale. On large-scale maps, deviations of private scales from the main (in view of their insignificance) are practically neglected, that is, the scale can be considered, like the scales of plans, as a constant.

The scales are shown in two ways: 1) by directly indicating the distance on the ground, corresponding to the unit of length on the map (for example, 1 cm on the map is equal to 10 km on the ground); 2) in the form of a fraction (the numerator of which is equal to one), showing the relationship between the distance on the map and the distance on the ground, for example, 1/1000000. This scale is called numerical; it is more convenient to write it, especially in a text set, in one line (1: 1,000,000 or 1/1,000,000); the sometimes used form of the fraction 1/1000000 is less convenient; for it you have to take small numbers that are difficult to read.

The order of transition from one type of scale to another is easy to learn from the following examples:

1. Given a numerical scale of 1: 1,000,000; find the number of kilometers on the ground, corresponding to 1 cm on the map.

One kilometer contains 100,000 cm. Divide the denominator of the numerical scale by this number and get the required value:

1,000,000 / 100,000 = 10, i.e. 10 km in 1 cm.

2. It is indicated that 1 cm on the map is equal to 10 km on the ground, find the numerical scale.

We multiply the number of centimeters in 1 km by 10 and get the denominator of the numerical scale: 100,000 * 10 = 1,000,000, that is, the numerical scale is 1: 1,000,000.

It is just as easy to transfer one type of scale to another in cases where the map is based on non-metric measures of length.

For example, it is indicated that 1 inch on the map is equal to 2 versts on the ground; find the numerical scale.

There are 500 fathoms in 1 verst, each fathom is 84 inches; therefore, the denominator of the numerical scale is: 2 * 500 * 84 = 84,000, that is, the numerical scale will be 1: 84,000.

Currently, in the USSR, where, as in most other countries, the metric system of measures has been adopted, the following scales are used: 1: 10000, 1: 25,000, 1: 50,000, 1: 100,000, 1: 200,000, 1: 500,000, 1: 1,000,000, etc. To get a correct idea of ​​the value of the above numerical scales, you should remember some of the numbers from the following table:

Numerical	Popular card name	1 cm on the map corresponds on the ground	1 cm 2 on the map corresponds to on the ground
1: 10 000	Ten thousandth card Twenty-five thousandth card Fifty-thousandth card Hundred thousandth map Two hundred thousandth card 500 thousandth card Million card	100 m	1 ha = 0.01 km 2 6.25 ha = 0.0625 km 2 25 ha = 0.25 km 2

In addition to metric scales, it is useful to know the scales in the old Russian measures (1 verst = 500 fathoms = 42,000 inches) and in the measures adopted in Great Britain, its colonies and some dominions (1 statute mile = 63,360 inches). The first ones were adopted for Russian maps of pre-revolutionary times (some of which have not lost their significance to this day); English maps are very popular thanks to the large territory of the British Empire.

The scale of Russian pre-revolutionary maps

Scales of English maps

Metric scales with their round numbers represent significant convenience in the practical use of maps; this predetermines their gradual widespread distribution.

Numerical scale mapping is required. The inconvenience of its absence can be judged from the example of some reference cards published in the Union of South Africa. These maps only indicate that one inch of the map corresponds to 1000 Cape genera in the area. For a map reader unfamiliar with the system of measures used in the Union of South Africa, this phrase provides very little. Reference books usually mention the English gender, equal to 5,029 m; and only in rare sources can one find that 1 Cape genus corresponds to 3 778, m, and get from this the numerical scale 1: 149 000 - an expression that is understandable to any user of the map.

In cartography, the word scale has two meanings. On the one hand, this is the relationship between the length of the line on the map and the length of the corresponding lines on the ground, on the other hand, it is a graphical construction for converting the distances on the map into the corresponding distances on the ground, expressed in any units of length. Such a graph is called a linear scale. It is constructed so that a certain length, taken from the map with a compass, can be directly scaled to the corresponding distance on the ground.

Example: given a map at a scale of 1: 63 360 (one mile in 1 inch). Before building a scale for measuring distances in kilometers. 1 km on the ground will be expressed on a map with a size of 100,000 / 63 360 = 1.58 cm. We lay aside segments equal to 1.58 cm on a straight line. We divide the extreme left of them additionally using parallel lines into 10 equal parts. For direct reading of the distance taken by the compass from the map, set one leg of the compass to a whole division so that the other leg falls on the leftmost segment that has additional divisions. The distance on the ground, read to scale, will be 2.14 km.

Measuring Distances on a Map Using a Linear Scale

In conclusion, we note that the use of linear scales gives relatively accurate results only on large-scale maps, on which the deviations of the partial scales from the main one are insignificant. On small-scale maps with significant deviations of private scales from the main one, a linear scale is usually absent (not drawn).

Scale(it. Maßstab, letters. "Measuring stick": Maß"measure", Stab"Stick") - in the general case, the ratio of two linear dimensions. In many areas of practical application, scale refers to the ratio of the size of the image to the size of the displayed object.

The concept is most common in geodesy, cartography and design - the ratio of the size of the image of an object to its actual size. A person is not able to depict large objects, for example, a house, in full size, therefore, when depicting a large object in a drawing, drawing or model, the size of the object is reduced several times: two, five, ten, one hundred, a thousand, and so on. The number showing how many times the depicted object is reduced is the scale. The scale is also used when depicting the microcosm. Man cannot portray living cell, which is viewed through a microscope, is life-size and therefore increases the size of its image by several thousand times. A number showing how many times the increase or decrease was made real phenomenon when displayed, it is defined as a scale.

Scale in surveying, mapping and design

Scale shows how many times each line plotted on a map or drawing is smaller or larger than its actual dimensions. There are three types of scale: numerical, named, graphic.

The scales on maps and plans can be represented numerically or graphically.

Numerical scale written in the form of a fraction, in the numerator of which there is one, and in the denominator - the degree of reduction of the projection. For example, a scale of 1: 5,000 shows that 1 cm on the plan corresponds to 5,000 cm (50 m) on the ground.

The larger is the scale with the smaller denominator. For example, a scale of 1: 1,000 is larger than a scale of 1: 25,000. In other words, if large scale the object is displayed larger (larger), with more small scale- the same object is rendered smaller (smaller).

Named scale shows what distance on the ground corresponds to 1 cm on the plan. It is recorded, for example: "In 1 centimeter 100 kilometers", or "1 cm = 100 km".

Graphic scales are subdivided into linear and transverse.

• Linear scale is a graphical scale in the form of a scale bar divided into equal parts.
• Transverse scale is a graphical scale in the form of a nomogram, the construction of which is based on the proportionality of the segments of parallel straight lines intersecting the sides of the corner. The transverse scale is used for more accurate measurements of line lengths on plans. The transverse scale is used as follows: measure the length on the lower line of the transverse scale so that one end (right) is on the whole division OM, and the left goes beyond 0. If the left leg falls between tenth divisions of the left segment (from 0), then raise both legs of the meter up until the left leg hits the intersection of some transvensal and some horizontal line. In this case, the right leg of the meter should be on the same horizontal line. The smallest CP = 0.2 mm, and the accuracy is 0.1.

Scale accuracy- this is a segment of the horizontal space of the line, corresponding to 0.1 mm on the plan. The value of 0.1 mm for determining the accuracy of the scale is taken due to the fact that this is the minimum segment that a person can distinguish with the naked eye. For example, for a scale of 1:10 000, the scale accuracy will be equal to 1 m.In this scale, 1 cm on the plan corresponds to 10,000 cm (100 m) on the ground, 1 mm - 1,000 cm (10 m), 0.1 mm - 100 cm (1 m).

The scale of images in drawings should be selected from the following range:

When designing master plans for large objects, it is allowed to use a scale of 1: 2,000; 1: 5,000; 1:10 000; 1:20 000; 1:25 000; 1:50 000.
In necessary cases, it is allowed to use the magnification scales (100n): 1, where n is an integer.

Scale in photography

Main article: Linear magnification

When photographing, the scale is understood as the ratio of the linear size of the image obtained on a photographic film or photosensitive matrix to the linear size of the projection of the corresponding part of the scene onto a plane perpendicular to the direction to the camera.

Some photographers measure scale as the ratio of the size of an object to the size of its image on paper, screen, or other media. The correct method for determining the scale depends on the context in which the image is used.

Scale is important when calculating depth of field. Photographers have access to a very wide range of scales - from almost infinitely small (for example, when photographing celestial bodies) to very large (without using special optics, it is possible to obtain scales of the order of 10: 1).

Macro photography is traditionally defined as shooting at a scale of 1: 1 or larger. However, with the widespread use of compact digital cameras This term also began to refer to photography of small objects located close to the lens (as a rule, closer than 50 cm). This is due to necessary change mode of operation of the autofocus system in such conditions, however, from the point of view of the classic definition of macro photography, this interpretation is incorrect.

Scale in Modeling

Main article: Scale (modeling)

For each type of scale (bench) modeling, scale series are defined, consisting of several scales of varying degrees of reduction, and for different types modeling (aircraft modeling, ship modeling, railway, automobile, military equipment) defined their own, historically formed, large-scale series, which usually do not intersect.

The scale in modeling is calculated by the formula:

Where: L is the original parameter, M is the required scale, X is the desired value

For example:

At a scale of 1/72, and the original setting is 7500 mm, the solution will look like;

7500 mm / 72 = 104.1 mm.

The resulting value is 104.1 mm, which is the desired value at a scale of 1/72.

Time scale

In programming

IN operating systems with time sharing, it is extremely important to provide individual tasks with so-called "real-time", in which the processing of external events is provided without additional delays and gaps. For this, the term "real time scale" is also used, but this is a terminological convention that has nothing to do with the original meaning of the word "scale".

In film technology

Main article: Accelerated filming # Time scale Main article: Slow motion shooting # Time scale

The time scale is a quantitative measure of the slowdown or acceleration of movement, equal to the ratio of the projected frame rate to the shooting frame rate. So, if the projected frame rate is 24 frames per second, and filming was performed at 72 frames per second, the time scale is 1: 3. A 2: 1 time scale means twice as fast as normal on-screen progress.

In mathematics

Scale is the ratio of two linear dimensions. In many areas of practical application, scale refers to the ratio of the size of the image to the size of the displayed object. In mathematics, scale is defined as the ratio of the distance on the map to the corresponding distance on the real terrain. A scale of 1: 100,000 means that 1 cm on the map corresponds to 100,000 cm = 1,000 m = 1 km on the ground.

How to calculate 1:50 scale?

The scale is used to place an area on the drawing, which is actually many times larger. At a scale of 1:50, all dimensions are taken 50 times smaller than they actually are. For example, the drawing is drawn at a scale of 1:50. On it, the size of 50 meters is taken as 1 meter. If you want to depict a bench 5 meters long, then in the figure its length will be 10 cm.This small scale is used in construction drawings to graphically depict a small area ( landscape design). Conclusion: when executing a drawing with a scale of 1:50, all original dimensions must be divided by 50.

Mirra-mi

A scale of 1 to 50 means that all objects and lines in the drawing are reduced 50 times than they actually are. That is, 1 cm in the drawing is 50 cm in reality. Therefore, while reading such a drawing, each centimeter must be multiplied by 50:

1 cm is 50 cm,

2 cm is 100 cm,

10 cm is 500 cm, etc.

A scale of 1:50 means that the object (drawing, map, graph, drawing, object, sketch, etc.), which we see is reduced in comparison with its original dimensions fifty times. Where the length is shown, for example, one centimeter in the original means fifty centimeters.

Zolotynka

To understand what the 1:50 scale is, consider an example: suppose we have a model car produced at a scale of 1 in 50. This means that the real car is 50 times larger than our model.

The same applies to maps: when we depict on a scale some terrain on a piece of paper or a computer screen, we reduce the distances by 50 times, but we will definitely preserve all the features of the terrain and all the proportions. The scale clearly shows the relationship between distances on the map and distances on the ground. This makes the map convenient for us, as we receive visual information with which we can easily calculate ground distances.

Those. in order to create a model at a scale of 1 to 50 (anything - object, terrain), you need to divide the real size by 50.

Azamatik

To do this, let's use an example.

A scale of 1 to 50 means, for example, that 50 kilometers is taken as 1 kilometer; 50 meters is taken as 1 meter; 50 centimeters as 1 centimeter, etc.

Let's take a real football field, which is 100 meters long and 50 meters wide.

To depict this field on a sheet of paper at a scale of 1 to 50, divide both the width and the length by 50 (50 m).

Therefore, this football field on a scale of 1:50 will be 2 meters long and 1 meter wide.

Moreljuba

The scale is a very necessary and important thing. It is very important when creating terrain drawings and maps. If we are talking about a scale of 1:50, then this means that all real objects when transferring them to our drawing should be 50 times reduced in size. In other words, the sizes of objects should be divided by 50. For example, if we need to draw an object 100 centimeters long on a drawing, we reduce it to 2 centimeters (100/50).

Quite simply, if this is some kind of drawing, then this means that all the details, for example, the model of the ship, are reduced by 50 times and to represent the true size of the ship from which this drawing was made, you will need to increase the model by 50 times, that is, multiply the size all parts by 50.

Raziyusha

If you need to make rooms, some object on a scale of 1:50, then you need to do it like this: divide each length by 50 cm, draw the result on paper. Let's say a wall with a length of 6 m in the drawing will be 12 cm long.How it is calculated:

6 m = 600 cm,

600: 50 = 12 cm.

Pollock tail

It turns out that all the objects in the picture are reduced by fifty times. In order to calculate the scale of the object, you need to measure the picture with a regular ruler after 1 cm. Multiply by 50. Actually, this is the real scale of the object.

The question is on the verge of fantasy. A scale of one to fifty is the ratio of one scale unit to contain 50 real scale units. For example, 1 cm of the established scale contains 50 cm of the real one.

Scale
(German Maßstab, from Maß - measure, size and Stab - stick), the ratio of the length of the segments in a drawing, plan, aerial photograph or map to the lengths of the corresponding segments in nature. The numerical Scale thus defined is an abstract number, greater than 1 in cases of drawings of small parts of machines and devices, as well as many micro-objects, and less than 1 in other cases, when the denominator of the fraction (with the numerator equal to 1) shows the degree of reduction in the size of the image of objects relative to their actual sizes. The scale of plans and topographic maps is a constant value; Scale geographic maps- variable value. For practice, a linear scale is important, that is, a straight line divided into equal segments with captions indicating the lengths of the corresponding segments in nature. For a more accurate drawing and measurement of lines on the plans, a so-called transverse scale is built. A transverse scale is a linear scale, parallel to which a series of equidistant horizontal lines are drawn, intersected by perpendiculars (verticals) and oblique lines (transversals). The principle of building and using a transverse scale. is clear from the figure given for a numerical scale of 1: 5000. The segment of the transverse scale, marked with dots in the figure, corresponds on the ground with a line 200 + 60 + 6 = 266 m. , sometimes without any inscriptions. This makes it easy to use it in the case of any numerical scale used in practice.
A scale of 1: 200 means that 1 unit of measurement in a figure or drawing corresponds to 200 units of measurement in space. For example: topographic map - the atlas of the Tver region has a scale of 1: 200000. This means that 1 centimeter on the map is equal to 2 kilometers on the ground.

Dmitry mosendz

A scale of 1: 200 means that 1 unit of measurement in a figure or drawing corresponds to 200 units of measurement in space. For example: topographic map - the atlas of the Tver region has a scale of 1: 200000. This means that 1 centimeter on the map is equal to 2 kilometers on the ground.

how to translate scales? pzh help and got the best answer

Answer from Elena [guru]
The scale shows how many times the distances on the plan are reduced in relation to the real distances.
for example the scale
1:1000
this means that in 1 cm on the map there are 1000 real cm, i.e. 10 meters
or
1: 500000
this means that in 1 cm on the map there are 500,000 real cm, i.e. 5,000 m or 5 km
The basic principle is this: if the left part is in mm, then the right one means the number of real mm, then you translate them into cm, m, or km,
if the left side is in cm, then the right side also shows the number of real cm, then you translate them into m or km
To get meters from cm, divide them by 100, the resulting meters are divided by 1000 - you will get km

M 1: 1, that is, 1 mm corresponds to 1 mm drawn on the drawing. M 1: 2, that is, 1 mm corresponds to 0.5 mm in the drawing (halving, any size, ideally, is drawn twice as small in the drawing). M 2: 1, that is, 1 mm corresponds to 2 mm in the drawing (an increase in two times in the drawing from the actual dimensions of the object).

Answer from AisiyaKonovalova[guru]
1. If this is a numerical scale, then you convert centimeters to meters, and then meters to kilometers. Divide by 100, and then by 1000. 1: 500,000. In 1 cm 5 km.
And if it's easier, then
If there are five zeros in the denominator after the first digit, then, covering 5 zeros with your finger, we get the number of kilometers on the ground, corresponding to 1 centimeter on the map. An example for a scale of 1: 500,000. In the denominator after the digit - five zeros, closing them, we get for the named scale: 1 cm on the map 5 kilometers on the ground.
If after the digit in the denominator there are less than five zeros, then, covering two zeros, we get the number of meters on the ground, corresponding to 1 centimeter on the map. If, for example, in the denominator of a scale of 1: 10,000 we close two zeros, we get: in 1 cm - 100 m.
To convert a named into a numeric one, you need to:
if written in 1 cm 5 km - add 5 zeros - 1: 500000

Scale 1: 100,000

1 mm on the map - 100 m (0.1 km) on the ground

1 cm on the map - 1000 m (1 km) on the ground

10 cm on the map - 10,000 m (10 km) on the ground

Convert the numerical scale of the map to the named one:

Solution:

For an easier translation of a numerical scale into a named scale, you need to calculate how many zeros the number in the denominator ends in.

For example, on a scale of 1: 500,000, there are five zeros in the denominator after 5.

If after the digit in the denominator there are five or more zeros, then, closing (with your finger, a fountain pen, or simply crossing out) five zeros, we get the number of kilometers on the ground, corresponding to 1 centimeter on the map.

Example for a scale of 1: 500,000

There are five zeros in the denominator after the digit. Closing them, we get for the named scale: 1 cm on the map 5 kilometers on the ground.

If after the digit in the denominator there are less than five zeros, then by closing two zeros, we get the number of meters on the ground, corresponding to 1 centimeter on the map.

If, for example, in the denominator of a scale of 1: 10,000 we close two zeros, we get:

in 1 cm - 100 m.

Answers:

1 cm - 2 km;

1 cm - 100 km;

in 1 cm - 250 m.

Use a ruler overlay on maps to help you measure distances.

Convert the named scale to numeric:

in 1 cm - 500 m

1 cm - 10 km

1 cm - 250 km

Solution:

For an easier translation of a named scale into a numerical one, you need to convert the distance on the terrain indicated in the named scale to centimeters.

If the distance on the ground is expressed in meters, then to get the denominator of the numerical scale, you need to assign two zeros, if in kilometers, then five zeros.

For example, for a named scale of 1 cm - 100 m, the distance on the ground is expressed in meters, therefore, for a numerical scale, we assign two zeros and get: 1: 10,000.

For a scale of 1 cm - 5 km, we assign five zeros to the five and get: 1: 500,000.

Answers:

Maps, depending on the scale, are conventionally divided into the following types:

topographic plans - 1: 400 - 1: 5,000;

large-scale topographic maps - 1:10 000 - 1: 100 000;

medium-scale topographic maps - from 1: 200,000 - 1: 1,000,000;

small-scale topographic maps - less than 1: 1,000,000.

Scale maps:

1:10 000 (1cm = 100m)

1:25 000 (1cm = 100m)

1:50 000 (1cm = 500m)

1: 100,000 (1cm = 1000m)

are called large-scale.

A fairy tale about a map on a scale of 1: 1

Once upon a time there was a Capricious King. Once he traveled around his kingdom and saw how great and beautiful his land is. He saw winding rivers, huge lakes, high mountains and wonderful cities. He became proud of his possessions and wanted the whole world to know about them. And so, the Capricious King ordered the cartographers to create a map of the kingdom. The cartographers worked for a whole year and finally presented the King with a wonderful map on which all mountain ranges, large cities and large lakes and rivers were indicated.

However, the Capricious King was displeased. He wanted to see on the map not only the outlines of mountain ranges, but also the image of each mountain peak. Not only large cities, but also small ones and villages. He wanted to see small rivers flowing into rivers.

The cartographers got to work again, worked for many years, and drew another map, twice the size of the previous one. But now the King wished that the passes between mountain peaks, small lakes in the forests, streams, peasant houses on the outskirts of the villages were visible on the map. Cartographers drew more and more new maps.

The capricious King died without waiting for the end of the work. The heirs, one after another, ascended the throne and died in turn, and the map was all drawn up and drawn up. Each king hired new cartographers to map the kingdom, but each time he was dissatisfied with the fruits of labor, finding the map insufficiently detailed.

Finally, the cartographers have drawn an incredible map !!! The map depicted the entire kingdom in great detail - and was exactly the same size as the kingdom itself. Now no one could find the difference between the map and the kingdom.

Where were the Capricious Kings going to keep their wonderful map? The casket for such a card is not enough. You will need a huge room like a hangar, and in it the map will lie in many layers. But is such a card needed? After all, a full-size map can be successfully replaced by the terrain itself ..))))
