- 1 Hz = 60 rpm
- 1 × 60 = 60 rpm
How to convert hertz to revolutions per minute
1 Hz = 60 rpm, so multiply by 60 to go from hertz (cycles per second) to revolutions per minute. Going the other way, 1 rpm = 0.0166666666667 Hz.
rpm = Hz × 60 Hz = rpm × 0.0166666666667
Worked example:
1 Hz = 60 rpm 5 × 60 = 300 rpm
