# What does the scale 1 50 000 mean?

SCALE AND CALCULATING DISTANCE a) The word scale expresses the scale in words, e.g. “One centimetre represents half a kilometre.” b) The ratio scale is written as a ratio or a fraction,e.g. 1:50 000 or 150000. This means that one unit (e.g. cm) on the map represents 50 000 of the same unit (cm) of the earth surface.

## What is a 1 25000 scale?

There is a standard ratio format for map scales e.g. “1: 25,000”. The first number is the unit on the map and the second number is the distance in real life of the same unit so 1: 25,000 means that 1cm on the map corresponds to 25,000 cm on the ground.

## What is the scale of 1 cm to 1 km?

For example, if the scale of the map was 1 cm = 1 km that means that a line on the map which is 1cm long is showing something which in real life measure 1 kilometre (which is 1,000 metres, or 100,000 centimetres).

## What does 1 250000 mean on a map?

For example, your map has a scale of 1:25 000, which means that every 1cm on the map represents 25 000 of those same units of measurement on the ground (for example, 25 000cm = 250 metres).

## What’s a bar scale?

Scale bars, or bar scales, are small graphics that indicate the proportions of a map to the original geographic area and help users measure distances on maps. While scale can be indicated as a ratio or in words (i.e. 1:10, or “One inch to ten miles”), scale bars allow users to measure distances in maps directly.

## How do you calculate scale?

How do you calculate scale? To scale an object to a larger size, you simply multiply each dimension by the required scale factor. For example, if you would like to apply a scale factor of 1:6 and the length of the item is 5 cm, you simply multiply 5 × 6 = 30 cm to get the new dimension.

## What does 1 24000 mean on a map?

The map scale is printed in the map legend. For example, a map scale indicating a ratio of 1:24,000 (in/in), means that for every 1 inch on the map, 24,000 inches have been covered on the ground. Ground distances on maps are usually given in feet or miles.

## How big is a grid square on a 1 25000?

Grid Squares: 1 blue grid square (4cm) represents 1 kilometre, which takes 15 minutes to walk and almost no time to drive. Amount of Detail: A 1:25,000 map will give you enough detail to do walking, running and off-road cycling plus micro and night navigation.

## What does 1 20000 mean on a map?

What does 1 20000 mean on a map? An example: on a map with the scale 1:20000, 3 centimeters accord to 0.6 kilometers in reality. 1 cm ⇒ 20000 cm. 3 cm ⇒ 20000 * 3 cm = 60000 cm = 600 m = 0.6 km. The scale is rounded to integers, the distance of the map to 0.1, the real distance to 0.001.

## How do you convert mm to KM?

The method to convert millimeters to kilometers is very simple. Simple way to do mm to km conversion is by dividing the millimeters value by 1000000.

## What scale is equivalent to 1cm to 5km?

We know that on a scale of 1cm, the actual distance is 5km. At An actual distance of 5km, the scale on the map is 1cm. cm. So, we get that the distance on the map will be 2.8cm if the actual distance is 14km.

## What does 1 12000 mean on a map?

USGS Map Scales 1:12,000 1 inch = 1,000 feet Accuracy +/- 33 feet 1:24,000 1 inch = 2,000 feet 1 inch = 7.5 minutes Accuracy +/- 40 feet 1:50,000 1 inch = 4,166 feet 1: 1,000 1 cm = 10 meters 1: 10,000 1 cm = 100 meters 1:100,000 1 cm = 1 kilometer.

## How accurate is an OS map?

For a “1:2500 scale Overhaul” map the comparable relative accuracy of the lines on the map is 1.2 metres (4 feet) relative to other lines within 200 metres (656 feet).

## What are the 2 types of scales?

There are two types of scales used in geography: map scales and relative scales. Each has a very different function, yet both also can work together.

## What are the four types of scales?

Each of the four scales (i.e., nominal, ordinal, interval, and ratio) provides a different type of information. Measurement refers to the assignment of numbers in a meaningful way, and understanding measurement scales is important to interpreting the numbers assigned to people, objects, and events.

## What scale map does the military use?

A military city map is a topographic map (usually at 1:12,550 scale, sometimes up to 1:5,000), showing the details of a city. It delineates streets and shows street names, important buildings, and other elements of the urban landscape important to navigation and military operations in urban terrain.

## What is the largest scale OS map?

The main scales used by Ordnance Survey (OS) for surveying are 1:1250, 1:2500 and 1:10 000. These are referred to as large scale maps, which is when features in the real world are portrayed larger on the map. OS also produce a number of mapping products at other scales, such as 1:25 000 scale and 1:50 000 scale.
