Azimuth Calculator: Bearing from Coordinates, Back-Azimuth and Conversion

Your details

Coordinates mode calculates azimuth from two lat/lon pairs. Convert mode translates a known azimuth.
Latitude of the departure point in decimal degrees. Positive = North, negative = South.
deg
Longitude of the departure point in decimal degrees. Positive = East, negative = West.
deg
Latitude of the destination point in decimal degrees.
deg
Longitude of the destination point in decimal degrees.
deg
Magnetic declination for your location. Positive = East declination (magnetic North is east of true North). Leave at 0 for true azimuth.

Azimuth 51.21 deg - NE (N51.21°E)

  • The bearing is 51.21 degrees (NE), expressed in quadrant notation as N51.21°E.
  • The back-azimuth (return bearing from destination to origin) is 231.21 degrees.
  • The two points are 5570.2 km (3461.2 mi) apart by great-circle path.
  • No magnetic declination was applied. Set the declination field to convert to a magnetic bearing for compass use.

Next stepTo use this bearing with a magnetic compass, enter your local magnetic declination. You can look it up at ngdc.noaa.gov/geomag/calculators/magcalc.shtml.
