Geography Tools

Choose the right calculator

Convert geographic coordinates, calculate geodesic distance, or work with map scale.

Latitude Longitude Converter

Convert WGS 84 latitude and longitude to UTM and back. Lambert-93 is a secondary France-specific approximation, not a U.S. coordinate system.

GPS Distance Calculator

Calculate surface geodesic distance, bearings, and a midpoint between GPS coordinates using the WGS 84 ellipsoid. Miles and kilometers are both shown; this is not route distance.

Map Scale Calculator

Calculate real-world distance, map distance, or a 1:N scale after converting the selected units. The existing engine also supports resize and print-size calculations.
