What is the part of a map that is used to measure distance?
A graphic scale is a ruler printed on the map and is used to convert distances on the map to actual ground distances. The graphic scale is divided into two parts. To the right of the zero, the scale is marked in full units of measure and is called the primary scale.
Is ground a distance?
The great-circle distance between two ground positions, as contrasted with slant distance or slant range, the straight-line distance between two points.
How do we calculate ground distance?
The ground distance between two points is determined by measuring between the same two points on the map and then multiplying the map measurement by the denominator of the RF or scale (Figure 5-1).

They can also help you determine the distance between two (or more) places. The scales on a map can be of different types, ranging from words and ratios to pictorial scales. Decoding the scale is the key to determining your distance. Here’s a quick guide on how to measure distances on a map.
How do you measure a mile on a map?
If the scale is a ratio (and looks like 1:100,000), you’ll multiply the map units by the number following the colon. For example, if you see 1:63,360, that means 1 inch on the map represents 63,360 inches on the ground, which is 1 mile.
Where do you find the scale on a map?
Find the scale for the map you’re going to use. They are typically located in one of the corners of the map. It might be pictorial—a ruler bar scale, or a written scale—in words or numbers. If the scale is a verbal statement (i.e. “1 inch equals 1 mile”), determine the distance by simply measuring it with a ruler.
