Distance Calculator

Calculate the exact distance between any two points on Earth using this simple tool. It measures great-circle distance (the shortest path between two points on a sphere) and displays results in both kilometers and miles.

How It Works

1. Click your first point on the map
2. Click your second point
3. View the distance measurement above the map

The red line shows the direct path between points. Click anywhere to start a new measurement.

FAQ

Q: How accurate is this?
A: The calculator uses the Haversine formula with Earth’s radius of 6,371 km, giving accurate great-circle distances.

Q: Why does the line look straight on the map?
A: The line appears straight on the 2D map but represents the shortest path on Earth’s curved surface.

Q: Can I measure longer distances?
A: Yes, you can measure any distance between points on Earth.

Q: Why might my measurement differ from road distances?
A: This tool measures direct “as the crow flies” distances, not road routes.
