How to Calculate Mileage?

To calculate the mileage from a map, measure the path you are going to take, in inches, then locate the scale of the map on the map key. The scale will tell you how many miles or feet there are in an inch. Multiply the number of inches by the number of miles or feet per inch, and that will give you the distance. If it is in feet, you will then have to divide by 5280.
