About Angle
A full turn is 360 degrees, 2π radians, or 400 gradians. Radians are the natural unit in maths, and most trigonometry functions expect them, so converting from degrees is a common first step: multiply by π/180. A right angle is 90°, or π/2 radians, about 1.5708. Surveying and artillery use mils, with 6,400 to a full turn.
