# Scale calculator: convert and calculate scale

The Scale Calculator is a versatile online tool designed to facilitate quick and efficient conversions between actual lengths and their counterparts on maps or in projects. This scale factor calculator simplifies the process of obtaining accurate values. Simply enter the scale you're using along with the length you're measuring, and the Scale Calculator provides an accurate result.

Moreover, it allows you to determine the appropriate scale factor if you know the actual length and its equivalent on a map or in a project. Our scale calculator is not only user-friendly but also readily available online on a convenient platform. Expedite your scale factor calculations and discover how straightforward and effective our Scale Calculator is.

## About Calculate Scale calculator

Scale is the ratio of distance between any two points on an object and the corresponding distance between those same two points on a model. For example, if the scale of a map is 1:50,000, that means that one unit on the map represents 50,000 units in real life.

Our scale calculator allows you, based on the given scale factor, to know the object's true size (if you specify its scale size) or scale size (if you specify its actual size). You can use the scale factor to convert lengths and widths from real life to map units, or vice versa.

The tool on this site (scale calculator) is an extremely useful tool that can help anyone determine the size of an object in any scale, and unit of length, from miles to millimeters.

The size of an object on a map or plan is often measured in scale. This number tells you how large or small an object is relative to its real-life size. If you have access to our scale converter, however, you don’t need to worry about these measurements. Simply enter the length of your object in centimeters (or any other measurement) and our calculator will give you an equivalent size in any other map or plan's scale. It doesn't matter if you're using centimeters, miles, feet, kilometers, inches - the calculator can work with all units of length!

### How to calculate scale factor?

A scale factor is used to indicate the proportion between the size of an object on a map and the size of that same object in real life. To calculate the distance between two points on a map, you need to know the map's scale factor.
There are two ways to calculate a scale factor:

• Use the length of an object on the map and compare it to the length of the same object in real life.
• Compare the distances between two points on the map to the real-life distances between those same two points.

Once you know the scale factor, you can use it to measure distances on the map. Just remember that you need to account for the fact that the scale factor might be different depending on the direction you're measuring in.

For example, if a map has a scale of 1:100, this means that for every 1 unit of measurement on the map, there would be 100 units of that same measurement in real life.

Our calculator allows you to easily calculate the scale factor. Enter the actual length and the length on the map or project.

### Summary

Use the scale converter above to find out the actual dimensions (or vice versa) based on the scale you enter. Or type in the actual dimensions and on a map, plan or blueprint to get an idea of what scale it is.

If you need help using this scale converter, take a look at the instruction page.
