Frequently asked questions
What is the Haversine formula?
The Haversine formula is an equation used in navigation to calculate the great-circle distance between two points on the surface of a sphere using their latitude and longitude coordinates.
How accurate is the Haversine distance calculation?
The formula assumes Earth is a perfect sphere with an average radius of roughly 6,371 kilometers. For most practical geographic calculations, the error margin is typically less than 0.5%.
Does this tool calculate road or driving distance?
No, it computes straight-line great-circle distance over Earth's curvature. It does not account for road networks, terrain elevation, or physical barriers.
What coordinate format does this calculator accept?
The tool accepts decimal degrees (DD). For example, 40.7128 for latitude and -74.0060 for longitude.
Is the Haversine distance calculator free to use?
Yes, this calculator is completely free to use online with no account creation or usage restrictions.
