Map scale is the ratio between a distance on a map and the corresponding distance on the ground. It is expressed in three main ways:

Ratio ScaleAlso known as Representative Fraction (RF). Unitless.1:50,000

Statement ScaleExpressed in words using specific units.1 cm = 1 km

Linear ScaleA visual bar line divided into equal segments.
