Map Distance Unit

Scale Ratio (1:X)

Formula

Real distance = map distance × scale ratio. Convert units as needed: 100 cm = 1 m, 100,000 cm = 1 km.

How do I use a map scale?

Multiply the distance measured on the map by the scale ratio. For example, 3 cm on a 1:50,000 map = 3 × 50,000 = 150,000 cm = 1.5 km.

What does 1:25000 mean?

A scale of 1:25,000 means 1 cm on the map represents 25,000 cm (250 m or 0.25 km) in reality.
