History: Ancient Babylonian origin, based on their sexagesimal system.
Current Use: Widely used for everyday angle measurements.
Radian (rad)
Definition: The SI unit of angular measurement.
History: Defined as the angle subtended by an arc equal to the radius.
Current Use: Used in mathematics, physics, and engineering.
Mil (angle) (mil)
Definition: A unit of angular measurement equal to 1/6400 of a circle.
History: Used in military and surveying applications.
Current Use: Used in artillery, surveying, and navigation.
