ℹ️ Technical Details

This calculator uses arbitrary precision arithmetic, which provides highly accurate distance calculations on the WGS84 ellipsoid. Unlike simpler methods like Haversine (which assumes a spherical Earth), this method accounts for Earth's ellipsoidal shape and provides as much accuracy as sought for any pair of points on Earth. Current machine-precision algorithms top out at about 15nm. This method can exceed that.

The calculation is performed using WebAssembly (WASM) compiled from Rust, providing near-native performance in your browser.
