On a planimetric map, the scale tells you the number of inches on the map that correspond to a specific number of actual miles in reality. For example, a scale of 1:24,000 indicates that one inch on the map represents 24,000 inches in the real world, which is equivalent to 2,000 feet or approximately 0.38 miles. This scale allows users to measure distances accurately on the map.
