What is a Reverse Bearing?

A reverse bearing (or back bearing) is a bearing pointing in the exact opposite direction from the original bearing. It's commonly used in surveying, navigation, and engineering to determine the direction opposite to the one initially measured.

How to Use This Calculator

  1. Enter the original bearing in degrees. This can be any value from 0° to 359.99°.
  2. Click the "Calculate" button to compute the reverse bearing.
  3. The calculator will display the reverse bearing, which will be the original bearing plus 180°, adjusted to fall within the 0° to 359° range.

Example

If you have an original bearing of 120.00°, the reverse bearing would be:

120.00° + 180° = 300.00°

Applications

Reverse bearings are essential in:

  • Surveying to verify measurements
  • Navigation for plotting courses
  • Engineering projects requiring exact opposite directions
  • Map creation and orientation
