Radians to Degrees Conversion

The radian is the SI unit for measuring angles, used in many areas of mathematics. One radian is the angle subtended at the center of a unit circle by an arc of unit length. So, one radian equals to 180/π degrees, or approximately 57.295779513°. The radian is defined in the SI as dimensionless, and its symbol is often omitted, especially in mathematical writing.

So, we come to the following radians to degrees conversion formula:

degrees = radians × 180° / π.

Along with degree, in our Radians to Degrees Conversion Calculator, you can choose a minute of arc (or arc minute) as measurement unit for angles. By definition,

1° = 60′.

And also, instead of radians, an angle can be expressed in units of π, using the following relation:

1π = 3.14159265359.
