Unit Information

Degree (°)

Definition: A unit of angular measurement equal to 1/360 of a full rotation.

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.

Gradian (grad)

Definition: A unit of angular measurement equal to 1/400 of a full rotation.

History: Developed with the metric system.

Current Use: Used in some surveying and engineering applications.

Arcminute (arcmin)

Definition: A unit of angular measurement equal to 1/60 of a degree.

History: Part of the traditional degree system.

Current Use: Used in astronomy and precise angular measurements.

Arcsecond (arcsec)

Definition: A unit of angular measurement equal to 1/60 of an arcminute.

History: Part of the traditional degree system.

Current Use: Used in astronomy for very precise measurements.
