Calculation Formula

Reverse Bearing = Original Bearing ± 180°

Where:
- If Original Bearing + 180° ≤ 360°, then Reverse Bearing = Original Bearing + 180°
- If Original Bearing + 180° > 360°, then Reverse Bearing = Original Bearing - 180°

What is a Reverse Bearing?

A reverse bearing is the direction that is exactly opposite to a given bearing. In surveying and navigation, this is useful for determining the return path or opposite direction of travel.

How to Use This Calculator

  1. Enter the original bearing in degrees (0-360). A bearing is typically represented as an angle measured clockwise from the north direction.
  2. Click the "Calculate" button to compute the reverse bearing.
  3. The calculator will display the reverse bearing, which will be in the range of 0-360 degrees.

Example

If you have a bearing of 135°, the reverse bearing would be:

Reverse Bearing = 135° + 180° = 315°

Applications

Reverse bearings are commonly used in:

  • Surveying applications to determine back-sight directions
  • Navigational planning for determining return routes
  • Mapping and construction projects requiring precise directional information
