How Far is 1 Degree Latitude?

Published by at 6:32 PM under Logistics


The first question that people ask us when they find out we’re training to traverse 10 Degrees Latitude is, “how far is 10 degrees latitude”?

Quick answer: 

1 degree latitude = approximately 69 miles (111 kilometers) of north-south distance.
10 degrees latitude = approximately 690 miles (1110 kilometers).

The distance varies (due to the earth’s slightly ellipsoid shape) from 68.7 miles at the equator to 69.4 at the poles. This is convenient since each minute (1/60th of a degree) is approximately one mile (source). Here is a neat graphic to show the variation in distance from the poles to the equater. As you can see the distance at the equater is shorter by 0.7 mile.
