Calculate the distance between two geographic coordinates using the Haversine formula.

This online calculator measures the distance between two cities using latitude and longitude.

This calculator converts various nautical measurement units. It includes conversions for speed and distance units. For speed, it can convert knots to miles per hour, kilometers per hour, feet per second or meters per second. For distance, it can convert nautical miles to miles, kilometers, cables, leagues, meters or feet.

Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.

Calculates the distance between two points of the Earth specified geodesic (geographical) coordinates along the shortest path - the great circle (orthodrome). Calculates the initial and final course angles and azimuth at intermediate points between the two given.

Calculates the prospect distance from height at observer and line of sight distance between two observers.
