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.
