About angle conversion
Method
How the turns to degrees converter works
Angles convert through the radian. A full turn is 2π radians = 360° = 400 gon = 6,400 NATO mils. A degree is 60 arcminutes, an arcminute 60 arcseconds.

FAQFrequently asked questions about angle conversion
How many degrees in a turn?
360.
What is half a turn?
180 degrees.
What is 2.5 turns?
900 degrees.
What is a turn in radians?
2π, about 6.283.
Why is the turn a useful unit?
Because rotation is naturally counted in revolutions, and 1 turn is less error-prone than 360 degrees.
