Revolutions per minute to hertz

1 revolution per minute in hertz
1 rpm = 0.016667 Hz
Hz = rpm × 1/60

To convert revolutions per minute to hertz, multiply by 0.01666666667. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works

The relationship is Hz = rpm × 1/60. Both units measure frequency, so the conversion is a fixed factor that never changes.

Common questions

How many hertz are in one revolution per minute?
One revolution per minute equals 0.016667 hertz. Hz = rpm × 1/60.
How do you convert revolutions per minute to hertz?
Use Hz = rpm × 1/60. So 10 rpm is 0.16667 Hz.
How many revolutions per minute are in one hertz?
One hertz equals 60 revolutions per minute, which is the reverse of the conversion above.
