How to Convert Turn to Radian

1 turn = 6.28319 radians

Radian = Turn × 6.28319

Example: 4 12 turn × 6.28319 = 28.274 rad

Reverse Conversion

To convert radians back to turns:

  • Remember, 1 radian equals 0.159155 turns.
  • To convert 28.274 rad to turn, multiply 28.274 x 0.159155, resulting in 4 12 turn.

4 12 turn is also equal to:

  • 1620 degree
  • 1800 gradian
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...
