How to Convert Revolution Per Minute to Radian Per Second

1 revolution per minute = 0.10472 radians per second

Radian Per Second = Revolution Per Minute × 0.10472

Example: 1800 rpm × 0.10472 = 188.5 rad/s

Reverse Conversion

To convert radians per second back to revolutions per minute:

  • Remember, 1 radian per second equals 9.5493 revolutions per minute.
  • To convert 188.5 rad/s to rpm, multiply 188.5 x 9.5493, resulting in 1800 rpm.

1800 rpm is also equal to:

  • 30 hertz
  • 0.03 kilohertz
About these units

Revolution per minute: Unit of rotational frequency; number of complete revolutions per minute.

Radian per second: SI unit of angular velocity; the rate of change of angular position in radians per second.

Frequently Asked Questions
