Azimuth Calculator – Accurate Angle Measurement Tool

Use this tool to calculate the azimuth angle between two geographic locations.

Azimuth Calculator

Use this calculator to compute the azimuth (bearing) from one geographic coordinate (latitude and longitude) to another. Azimuth is the angle between the north reference point and the line connecting the two points on a sphere (earth).

How to Use the Azimuth Calculator:

  1. Enter the latitude and longitude of the first point into “Latitude (Point 1)” and “Longitude (Point 1)” fields.
  2. Enter the latitude and longitude of the second point into “Latitude (Point 2)” and “Longitude (Point 2)” fields.
  3. Click the “Calculate” button.
  4. The azimuth result will be displayed in degrees in the “Result” field.

How It Calculates:

The formula used to compute the azimuth is based on spherical trigonometry. It involves the following steps:

  1. Convert the latitudes and longitudes from degrees to radians.
  2. Calculate the difference in longitude (delta longitude) between the two points.
  3. Compute the values of x and y using trigonometric functions.
  4. Calculate the bearing using the atan2 function, convert it back to degrees, and normalize it to a 0-360 degree range.


  • This calculator assumes a perfect sphere model for the Earth, which is not completely accurate as the Earth is an oblate spheroid.
  • Accuracy may decrease for distances that span large portions of the globe due to the curvature of the Earth.
  • The calculator does not account for any obstacles or geographic features between the two points.
