Information
What is this?
Calculate the geodesic distance (over the Earth's ellipsoid) between two points using professional mathematical formulas.
Available formulas:
- Vincenty: Sub-millimeter precision. Uses the WGS84 ellipsoid.
- Haversine: Fast. Assumes a spherical Earth (error ~0.3%).

Frequently Asked Questions
Haversine assumes the Earth is a sphere; it's faster but less accurate. Vincenty treats the Earth as an ellipsoid; it's slower but has millimeter-level precision. Use Vincenty for professional projects.
Results are shown simultaneously in kilometers, statute miles, meters, and nautical miles. Ideal for navigation, aviation, and surveying.
Yes, the tool calculates distances of any magnitude on the Earth's surface, from meters to intercontinental distances of thousands of kilometers.
