Detailed explanation-1: -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.
Detailed explanation-2: -The scale of a map shows the ratio between the distances on the map and the corresponding distances in reality. For example, a map of scale 1:50, 000 shows a distance of 50, 000 cm (or 500 m) as 1 cm on a map. A 1:25 scale model of a building with a height of 30 m has a model height of 1.20 m.
Detailed explanation-3: -Map scale can be defined as the ratio between the distance on a printed map and the distance of the same stretch in the terrain. A 1:50, 000 scale map means that 1 cm on the map represents 50, 000 cm (i.e. 500 m) in the terrain.
