Advice 1: How to calculate scale

On any geographical map you can see about the following inscription: "Scale 1:100 000". Usually the first number is 1, and the second may vary. If it isn't there, then definitely there's a little Ticker, divided into equal periods, or nomogram. These signs designate the ratio of the size of an object on the map or plan to its real size.
Scale is the size ratio of the map distance on site
You will need
  • Tape measure or surveyor's compass
  • Line
Instruction
1
If you have a plan, which accurately plotted the various objects and you need to find out the extent to which the plan is made – start with measurements. Select the object that is nearby. Obmerte him on the plan and record the results.
2
Measure the actual object. Use the tape measure. In order to avoid mistakes, make the peg and hook a loop of tape. Hammer a stake into the ground so that the zero mark roulette was at the starting point of the length or width of the object.
3
Define the scale. The only record of its figures. Note the size of the object on the plan, then the one that happened when measuring on site. For example, you have got that barn 5 metres in length on the plan is 2, 5 cm. Move the meters to centimeters. So you have 2, 5 cm containing 500 cm. Calculate how many centimeters of the territory contained in 1 cm on the plan. For this larger number, divide by less. Receive 2.5:500=1:200, i.e. 1 cm in the plan corresponds to 2 metres on site.
4
In order to determine the scale more accurately, take a few measurements. For example, obmerte barn on the site and distance from the gate to the pond. Plans are different, and the size of an object can be applied not accurately. If there are discrepancies, take another measurement. The image of the object that does not match the other two, adjust the plan.
Note
The larger the scale, the smaller the denominator, where it is recorded. 1:100 is more than 1:2 000.

To measure an object easier with a helper. If there is no helper, and the peg by hand was not, firmly push the tape measure against the wall of the object. It is most convenient to measure on the ground – for example, on the bottom of the wall.

Advice 2: How to translate the scale

With the need to represent the actual size shown in the drawing of the object one is confronted in the school. The lesson of drawing is necessary to draw a detail at a scale of 1:2 or 1:4, geography lesson – count the exact distance between the two cities. To cope with the task, you need to know how to translate the scale.
Measure the distance on the map
You will need
  • - geographical map;
  • - detail drawing;
  • calculator;
  • - drawing utensils.
Instruction
1
If you need to draw details at a scale of 1:1, meaning that 1 cm of the surface will correspond to 1 cm on the drawing. Measure the surface you need to paint a picture and draw it on paper in full size.
2
In the drawing are applied on a different scale. 1:2 means that the part on the drawing must be two times smaller than in reality. If you specify a scale of 1;4, this means that 1 cm on the drawing is 4 cm details. Sometimes Vice versa. Very tiny object can be drawn, for example, on a scale of 4:1, 10:1, etc. If you see a similar symbol, it means that the figure of the subject in four or ten times more than it actually is.
3
In geography also requires the translation of the scale. We consider a geographical map. In one of the bottom corners you will see a line either with numbers or just numbers, e.g. 1:50 000. The numbers, of course, more than the drawing, but the principle of their translation is exactly the same, that is, in the above example, 1 cm of the map represents 50 000 cm of the earth's surface, i.e. 500 m. This map is a relatively large scale. Looking at the world Atlas, you will see a much more respectable numbers.
4
Quite often we need to translate the scale is not linear measures and square, that is, to determine how many square centimeters. To do this, measure the desired area in any convenient way. For example, using the palette. To find out the real area, it is necessary to translate the linear scale into a square, that is, to build the number of inches contained in 1 cm of the card, in a square. The resulting number multiply by the area of land depicted on the map. Thus you find out how many square meters is the territory you are interested in.
5
It is sometimes necessary to translate the scale of the volumetric object. For example, in class work, the teacher can give the task to produce the item depicted on the technical drawing at a certain scale. You need to know how much material it will need. The principle of transfer will be the same. First, find out how many actual inches corresponds to the corresponding line in the drawing. Determine the amount of detail in the drawing. It's a simple mathematical problem, the solution depends on the form of specific details. The value to which the scale, build the cube and then multiply by the volume of the part, calculated according to the drawing.
Useful advice
You can try yourself to draw a simple plan by a certain scale. For example, a scale of 1:10 for room plan will fit perfectly. Measure length of walls and large objects, determine their relative positions and draw a plan in accordance with the received data.
