About these units

Turn: A turn (revolution) represents a full rotation.It is a convenient unit in mechanics, robotics, control systems, animation, and computer graphics for expressing rotations.

Radian: The radian (rad) is the SI derived unit of plane angle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius.Although mathematically dimensionless, th...
