Scale

Ratio of map distance to Earth distance. Thus, in a 1:24,000 scale map, one centimeter, inch, or foot equals 24,000 centimeters, inches, or feet on the ground. Graphic scales typically show equivalent map and ground distance in the form of a line or bar.

Scale 1) A series of marks at regular intervals for the purpose of measuring (scale of an instrument, for example, a thermometer). 2) System of units for measuring. 3) Proportion between the size of something and the map, diagram, etc. which represents it. 4) Order of magnitude of a phenomenon or of a meteorological parameter.
