Great-Circle Distance (Haversine)Live

Controls

Presets

The shortest route between two points on Earth is a great-circle arc, not a straight line on a flat map. The haversine formula computes that distance from latitude and longitude, staying accurate even for nearly antipodal points. It powers flight planning, GPS, and every "distance between" feature — and explains why polar routes look curved on a Mercator map.

Governing equation

Reading this result: A great circle changes heading as you travel, so the 51-degree initial bearing is not the heading you keep — that constant-heading path (a rhumb line) would be longer.
