Azimuth Calculator
Enter the latitude and longitude of two points to calculate the azimuth (compass bearing) from the first point to the second.
What this calculator does
An azimuth is the compass bearing from one point to another, measured clockwise from true north (0° to 360°). This calculator finds the azimuth from a starting point to a destination point given both locations’ coordinates.
How the calculation works
It uses the standard great-circle initial bearing formula, which accounts for the curvature of the Earth: it converts both coordinates to radians and computes the angle using spherical trigonometry (atan2 of the difference in longitude combined with both latitudes), then normalizes the result to 0-360 degrees.
The back azimuth (the bearing for the return trip) is simply the forward azimuth plus or minus 180 degrees. This is the standard method used in navigation, surveying, and orienteering.
