Enter the current bearing (degrees) into the Reverse Bearing Calculator. The calculator will evaluate and display the Reverse Bearing. 

Reverse Bearing Formula

The following formula is used to calculate the Reverse Bearing.

RB = CB + 180
  • Where RB is the Reverse Bearing (degrees)
  • CB is the current bearing (degrees) 

To calculate a reverse bearing, simply add 180 degrees to the current bearing.

How to Calculate Reverse Bearing?

The following example problems outline how to calculate Reverse Bearing.

Example Problem #1:

  1. First, determine the current bearing (degrees).
    • The current bearing (degrees) is given as: 50.
  2. Finally, calculate the Reverse Bearing using the equation above: 

RB = CB + 180

The values given above are inserted into the equation below and the solution is calculated:

RB = 50 + 180 = 230 (degrees)

Example Problem #2: 

For this problem, the variables required are provided below:

current bearing (degrees) = 80

Test your knowledge using the equation and check your answer with the calculator above.

RB = CB + 180 = ?
