Answer: scale
Explanation: Hi, map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground.
Using a map scale is important when trying to determine the actual distance represented on a map. Most map scales are in terms of miles per inch. The ratio between miles and inches will depend on how large an area the map is representing.
