Degrees are used to measure a plane angle and represent 1/360 of a full rotation. They are fairly easy to convert to turns as one turn equals 360 degrees (so a full circle). Degree to radian conversion requires using a calculator as 1 radian equals 1/2π. The close estimation of this value in degrees is 57.296°. Another, not so common but still frequently used unit is the gradian. 1 gradian equals 1/400 of a turn or 9/10 of a degree.
