How to Calculate Map Scale

Maps are important instruments for navigating the world round us. They supply a visible illustration of an space, exhibiting us the situation of roads, buildings, and different options. However how do we all know how far aside issues are on a map? That is the place map scale is available in.

Map scale is the connection between the space on a map and the corresponding distance on the bottom. It is normally expressed as a ratio, resembling 1:24,000. Which means that one unit on the map represents 24,000 models on the bottom. For instance, if the map scale is 1:24,000 and the space between two factors on the map is 2 centimeters, then the precise distance between these two factors on the bottom is 24,000 centimeters, or 2.4 kilometers.

Now that you recognize what map scale is, let’s check out tips on how to calculate it.

Calculate Map

Observe these steps to calculate map scale:

Measure the space on the map.
Convert the map distance to the identical models as the bottom distance.
Divide the bottom distance by the map distance.
Simplify the ratio till it’s in its lowest phrases.
Categorical the size as a consultant fraction.
Label the size with the suitable models.
