Hertz to Revolutions per Minute
1 Hz = 60 rpm
How to convert hertz to revolutions per minute
Enter the value in hertz (Hz) above and the equivalent in revolutions per minute (rpm) updates as you type. This conversion comes up when audio work: musical pitch and equipment specs (Hz, kHz).
- Concert pitch A above middle C: 440 Hz → that is 26400 rpm in revolutions per minute.
- European mains power: 50 Hz, US: 60 Hz → that is 3000 rpm in revolutions per minute.
Typical situations: radio: broadcast bands in kHz/MHz; electronics: mains frequency (50 Hz vs 60 Hz countries) and CPU clocks (GHz).
You can also convert in the other direction: Revolutions per Minute to Hertz
Hertz to Revolutions per Minute conversion table
| Hertz (Hz) | Revolutions per Minute (rpm) |
|---|---|
| 1 | 60 |
| 2 | 120 |
| 5 | 300 |
| 10 | 600 |
| 25 | 1500 |
| 50 | 3000 |
| 100 | 6000 |
Watch out for
- kHz vs MHz in radio: a factor of 1,000; FM is around 100 MHz, AM around 1 MHz
- Mains frequency does not affect voltage, which is why 50/60 Hz devices are often but not always interchangeable
