Midpoint Coordinates Calculator

Midpoint Coordinates Calculator

Finding the true midpoint between two coordinates on a sphere isn't as simple as averaging latitude and longitude directly - this calculator computes the actual midpoint along the great-circle path, the shortest route over Earth's curved surface.

Example

Midpoint between New York City (40.7128, -74.0060) and London (51.5074, -0.1278):

Midpoint ≈ (52.37, -41.29)

Why Not Just Average Lat/Lon Directly?

Simply averaging two latitude and longitude values gives an incorrect result for anything but very close points or points lying exactly along the same meridian - it fails to account for Earth's curvature and can produce a "midpoint" noticeably off the actual shortest path between the two locations, especially over long transatlantic or transpacific distances.

Real-World Use

This is the same calculation aviation flight planning software and maritime navigation systems use to find a genuinely central waypoint between two locations - useful for planning a meeting point between two travelers, or finding the halfway point along a long-distance flight route.
