The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. A map is classified as small scale or large scale or sometimes medium scale. Small scale refers to world maps or maps of large regions such as continents or large nations. In other words, they show large areas of land on a small space. They are called small scale because the representative fraction is relatively small.  Use these tools to calculate equivalent units from a map scale, or calculate a map scale based on equivalent units.

Enter the representative fraction of your map to calculate equivalent units.

If the map scale is 1:24,000, enter 24,000 here.

Feet

Meters

Miles

Kilometers

#### Inches:

Inches = One Mile
Nautical Miles per Inch
Inches = Nautical Mile

#### Metric:

Centimeters equals One Kilometer
Kilometers per Centimeter

This calculator will calculate the representative unit equivalents based on the map scale..

Enter the equivalent units of your map to calculate the map scale.

For example, enter in 1 inch equals 2,000 feet to calculate the resulting map scale.
