About this tool

Accepts decimal degrees (37.7749, -122.4194), degrees-minutes-seconds (37°46'30"N), or a paste of either format. Outputs both representations side by side.

Distance is the great-circle (Haversine) distance on a sphere with WGS-84 mean radius of 6,371 km — accurate to within a few tenths of a percent for any two points on Earth.
