Haversine Method
Our calculator implements the Haversine formula, which calculates the shortest distance between two points on a sphere. This is the most accurate method for non-complex geographical distance queries.
Spherical Trigonometry
By accounting for the Earth's average radius (6,371 km), we provide results that are significantly more accurate than standard Cartesian distance calculations for long-range spatial analysis.
