Remember the distance in the extension is always read from right to left. Align tick mark (c) with zero and then measure the distance between tick marks (a) and (c). The distance between tick marks (a) and (c) is 420 meters. The total ground distance between start and finish points is 6,420 meters.

- Measure Distance on a Map
The measurement of an area calculates and displays the area between three or more points on the map. To start measuring an area: Press the ‘Measure distance’ button (button turns blue)
Performance Steps. 1. Identify the scale of the map. The map scale is the ratio (1:50,000) of the distance on map (1 inch) relative to the distance on the ground (usually 50,000 inches). 2. Convert a straight-line map distance to miles, meters, or yards using the map's bar scale (Figure 071-329-1008-1). Figure 1.
Map scale is ALWAYS shown on a map. Shown below is a British M726, 1:50,000 scale map with the ratio and scale lines shown. Estimating and measuring distance. As maps show a grid and have scale lines, it is possible to estimate or measure distances for use on the ground or on a map.
(a) Measure the distance between two points on the map—map distance (MD). (b) Determine the horizontal distance between these same two points on the ground—ground distance (GD). (c) Use the RF formula and remember that RF must be in the general form: RF. =
