### How to Calculate Ratios: A Step-By-Step Guide ...

This makes it easier to use the ratio to inform your calculations. Ratios are used in maps to provide scale. Usually expressed as 1:10,000 or similar, this tells you that for every 1 unit on the map, the real distance is 10,000 units. If you measure 1 cm on the map, the real distance would be 10,000 cm (or 100 m).
