# Azimuth vs. Bearing — What's the Difference?

Edited by Tayyaba Rehman — By Maham Liaqat — Updated on April 14, 2024
Azimuth is a full-circle measurement from due north in degrees, used in various fields like navigation, while bearing is often expressed in degrees from north or south towards east or west and is mainly used in navigation.

## Key Differences

Azimuth is measured in degrees with a full 360-degree circle, starting from due north and moving clockwise, useful in mapping and astronomy, whereas bearing describes the direction of one point from another using the cardinal directions as references, typically in navigation.
The azimuth is a more universal measurement applied across various scientific and technical fields, providing a precise angle from 0° to 360° from a reference direction, on the other hand, bearing is more specific to navigation and often involves descriptions combining cardinal directions and degrees.
When using azimuth, one often needs a complete understanding of the directional circle, as any direction can be described from 0° to 360°, whereas bearings are often simpler, referencing only the angle relative to the nearest cardinal direction (e.g., 45° NE).
In practical applications like using a compass, azimuth readings can directly align with compass degrees, while bearings are used to navigate relative to the current path or towards a specific landmark.
While both terms describe directional angles, azimuth can be used in more precise applications such as satellite dish alignment or military targeting, whereas bearing is frequently used in sea or land navigation to describe general directions.

#### Azimuth

An azimuth ( (listen); from Arabic اَلسُّمُوت as-sumūt, 'the directions', the plural form of the Arabic noun السَّمْت as-samt, meaning 'the direction') is an angular measurement in a spherical coordinate system. The vector from an observer (origin) to a point of interest is projected perpendicularly onto a reference plane; the angle between the projected vector and a reference vector on the reference plane is called the azimuth.

#### Azimuth
