360 (three hundred [and] sixty) is the natural number following 359 and preceding 361.

In mathematics

A turn is divided into 360 degrees for angular measurement. 360° = 2 π rad is also called a round angle. This unit choice divides round angles into equal sectors measured in integer rather than fractional degrees. Many angles commonly appearing in planimetrics have an integer number of degrees. For a simple non-intersecting polygon, the sum of the internal angles of a quadrilateral always equals 360 degrees.
