Angle tools
Convert between degrees, radians, gradians and the arc subdivisions. If you are writing code, remember that Math.sin, Math.cos and Math.tan take radians in essentially every language — degrees must be converted first.
About angle conversion
Angle units differ only in how finely they divide a full turn: 360 degrees, 400 gradians, or 2π radians. The radian is the mathematically natural choice and the one programming libraries expect.
