Answer: The map scale

Explanation: A Map Scale is defined as the ratio of the distance on a map to the distance on the surface the map represents. For example, 1 centimetres on a map represents 10 kilometres on the surface of the Earth. What this means is that for every 1 centimetre you measure on the map, that equates to 10 kilometres on Earth / real life.
