Distance between coordinates
Two points. One transparent calculation.
Estimate the shortest surface arc, without a map or an API.
A clearer sense of distance.
Enter two coordinate pairs to see their estimated surface separation.
A useful estimate, with clear limits.
This model omits terrain and the Earth’s ellipsoidal shape. It is not a route planner or a safe navigation instrument. Decimal places are not an accuracy promise.
