The full circle or full turn or cycle or rotation or revolution uses k = 1/2pi, making the angle of 1 full circle = 2pi rad = 4 right angles = 400 gon = 360°.
In mathematics and physics, the radian is a unit of angle measure. It is the SI derived unit of angle. It is defined as the angle subtended at the center of a circle by an arc of circumference equal in length to the radius of the circle. Angle measures in radians are often given without any explicit unit. When a unit is given, sometimes the abbreviation rad is used, sometimes the symbol c (for "circular").
