About this tool

Calculates the shortest distance between two points on the surface of a sphere, such as the Earth. The tool requires users to input geographical coordinates—latitude and longitude—for both starting and ending locations. Using these parameters, the Great Circle Calculator applies complex spherical trigonometry formulas to determine the bearing (the direction traveled) and the actual great-circle distance along the curved path connecting the points. Navigators, cartographers, travel planners, and researchers using global data sets find this calculator useful for accurate route mapping. It provides a precise measure of the true shortest path between two coordinates, which is critical when calculating flight paths or maritime routes that must account for the curvature of the planet.
