# Question: How do I get my azimuth back?

Contents

Back azimuths are calculated as follows: If the original azimuth is less than 180 degrees you ADD 180 degrees to the original azimuth, thus an azimuth of 45 degrees (<180) will have a back azimuth of 225 degrees. If the original azimuth is greater than 180 degrees you SUBTRACT 180 degrees from the original azimuth.

## What is the back azimuth of 135?

An azimuth is the direction of travel indicated on a compass and expressed in degrees (135 degrees). A bearing describes an angle or difference from a point. On the compass, you use the north and south for the reference. An azimuth of 135 degrees is the same as the bearing 45 degrees East of South (S 45 E).

## What is the back azimuth of 20 degrees?

For example, if your azimuth were 200 degrees, adding 180 degrees would result in a back azimuth of 380 degrees, whereas subtracting 180 degrees would result in a back azimuth of 20 degrees. The back azimuth 380 degrees is obviously greater than the number of degrees in a circle—20 degrees greater.

## How do you calculate back azimuth in Mils?

## What is the purpose of a back azimuth?

Plotting a back azimuth allows you to go in exactly the opposite direction from your original direction (azimuth) of travel. Back azimuths must be calculated before you can plot them on a map.

## What does back azimuth mean?

A back azimuth is a projection of the azimuth from the origin to the opposite side of the azimuth circle. A back azimuth is calculated by adding 180° to the azimuth when the azimuth is less than 180°, or by subtracting 180° from the azimuth if it is more than 180°.

## What is the point of a back azimuth?

Plotting a back azimuth allows you to go in exactly the opposite direction from your original direction (azimuth) of travel. Back azimuths must be calculated before you can plot them on a map.

## How do you find forward and backward azimuth?

A back azimuth is calculated by adding 180° to the azimuth when the azimuth is less than 180°, or by subtracting 180° from the azimuth if it is more than 180°. For example, if an azimuth is 320°, the back azimuth would be 320° - 180° = 140°. If the azimuth is 30°, the back azimuth would be 180° + 30° = 210°.
