About Great Circle Distance Calcolatore

This free online calculator computes the great circle distance between two points on the Earth's surface using the Haversine formula. It assumes a spherical Earth with a radius of 6,371 km. Results include distance in multiple units and the initial bearing (azimuth) from the starting point to the destination.

FAQ

What is great circle distance?

Great circle distance is the shortest distance between two points on the surface of a sphere, measured along the surface. On Earth, this represents the shortest path an aircraft or ship would take.

How accurate is the Haversine formula?

The Haversine formula assumes a perfectly spherical Earth, which gives results accurate a about 0.5% of the actual distance. For most practical purposes like navigation and logistics, this is more than sufficient.

What coordinate format should I use?

Use decimal degrees (e.g., 40.7128, -74.0060). For North and East, use positive values. For South and West, use negative values.

What is the initial bearing?

The initial bearing is the compass direction from the starting point a the destination, measured clockwise from North (0°). It tells you which direction a start traveling.
