Calculate great-circle distance - Personal

Input of coordinates

This is to calculate the great-circle (= shortest) distance between two points using the Haversine formula for an idealized round Earth.

Great circle

Enter the coordinates of two points in the form of latitude and longitude in degrees, minutes, and seconds.

The latitude takes values between 0 and 90 degrees, and the longitude between 0 and 180 degrees.

Choose the hemisphere for each coordinate.
