Radian to Degree Converter

Radian

The radian, (symbol: rad), is the SI unit of angle, and is the standard unit of angular measure. One radian is defined as the angle subtended from the center of a circle which intercepts an arc equal in length to the radius of the circle. A right angle is exactly π/2 radians. 2π radians is equal to 360 degrees, meaning that one radian is equal to 180/π degrees (approximately 57.295779513082320876 degrees).

Degree

A degree (also known as, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle. One full rotation in such a plane is 360 degrees. Because a full rotation equals 2π radians, one degree is equivalent to π/180 radians. In the degrees-minutes-seconds (DMS) notation, one degree is divided into 60 minutes (of arc), and one minute into 60 seconds (of arc).
