All distances measured by using the map and graphic scales are flat distances. Therefore, the distance measured on a map will increase when actually measured on the ground. This must be taken into consideration when navigating across country.

Measurement of distance. a. Take a ruler or the edge of a piece of paper and mark on it the straight-line distance between your two points (Figure 5-30). b. Then, put the ruler or the paper just under one of the bar scales and read the ground distance in miles, meters, or yards.
The scale of the map permits the user to convert distance on the map to distance on the ground or vice versa. The ability to determine distance on a map, as well as on the earth’s surface, is an important factor in planning and executing military missions.
1. Identify the scale of the map. The map scale is the ratio (1:50,000) of the distance on the map (1 inch) compared to the distance on the ground. (usually 50,000 inches). 2. Convert a straight-line map. distance to miles, meters, or yards.
The scale note is a representative fraction that gives the ratio of a map distance to the corresponding distance on the earth’s surface. For example, the scale note 1:50,000 indicates that one unit of measure on the map equals 50,000 units of the same measure on the ground.
Soldiers must know how to determine locations of points on a map, measure distances and azimuths, and identify symbols on a map. They must also be able to determine the elevation and relief of areas on standard military maps.
