UnitAngle
A unit of measure for planar angle and rotation.
Declaration
class UnitAngleOverview
You typically use instances of UnitAngle to represent specific quantities of planar angle using the NSMeasurement class.
Angle
Angle is a quantity of rotation. The SI unit for angle is the radian (rad), which is dimensionless and defined to be the angle subtended by an arc that is equal in length to the radius of a circle. Angle is also commonly expressed in terms of degrees (°) and revolutions (rev).
The UnitAngle class defines its baseUnit() as degrees, and provides the following units, which are initialized using UnitConverterLinear converters with the specified coefficients:
