The root word for "azimuth" is gotten from the Arabic language "as-samt," whose plural is "as-suit", and it means the way or direction. Hence, azimuth simply refers to the usage of the compass to determine a direction. The reference happens to be north, which is on 0 or 360 degrees. Then it makes a calculation in a clockwise direction from the 0 degrees, and its unit is in degrees.
Therefore, you will discover that the East makes 90 degrees; the South is 180 degrees, while the West measures 270 degrees. On the other hand, we can define bearing as an angle of separation majorly between two points. Bearing is considered to be general, and it is of several uses and meanings depending on its application.
Bearing is also mostly measured in degrees, and in mils times. Bearing takes its approach of measurement by making reference to the four cardinal points, that is, the north, south, east, and west, in the arrangement of preference. For example, 40 degrees on azimuth would be N40°E in bearing.
