  • To convert 12 turn to°, multiply 12 x 360, resulting in 180°.

180 ° is also equal to:

  • 3.1416 radian
  • 200 gradian
About these units

Degree: The degree (°) is a non-SI unit of plane angle defined as 1/360 of a full rotation.It is accepted for use with the SI due to its long-standing practical importance in navigation, surveying, engineeri...

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.
