How flight distance is measured

Aircraft fly the shortest route over the curved surface of the Earth — a great-circle path. The calculator uses the Haversine formula to compute this true distance.

Great-circle route

The shortest path between two points on a sphere. That is why flights between Europe and North America arc far north.

Three units

Results are shown in statute miles (road/consumer), kilometers (metric) and nautical miles (aviation standard).

Bigger than the map

A straight line on a flat map can be up to 40% longer than the real great-circle flight distance.

How long will the flight take?

Now that you know the distance, estimate the flying time with typical cruising speeds.
