Degree (angle)

A **degree** (in full, a **degree of arc**, **arc degree**, or **arcdegree**), usually denoted by **°** (the degree symbol), is a measurement of plane angle, representing of a full rotation. It is not an SI unit, as the SI unit for angles is radian, but it is mentioned in the SI brochure as an accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians.
