Frequently Asked Questions

The tool uses the Haversine formula to calculate the great-circle (straight-line) distance between two points on Earth, based on their latitude and longitude coordinates. This gives the shortest distance over the surface of the sphere.

No. The distance shown is the straight-line (as-the-crow-flies) distance. Actual driving distances will be longer due to roads, terrain, and detours. Actual flight paths may also differ due to air corridors and wind patterns.

The estimates are rough approximations. Flight time assumes an average cruising speed of 900 km/h and does not include takeoff, landing, or layovers. Driving time assumes a constant 80 km/h average and does not account for traffic, stops, or road conditions.
