Hertz to RPM – convert Hz to revolutions per minute
Convert hertz to RPM (Hz to revolutions per minute) to link electrical frequency with the rotational speed of motors, fans, pumps and other rotating equipment. This page opens the main frequency converter with Hz → rpm pre-selected.
Open the interactive Hz → rpm converter:
Use main converter (Hz → rpm) or switch to rpm → HzOn the homepage you can also convert between hertz, kilohertz, megahertz and gigahertz using the same frequency engine.
Quick reference: Hz to RPM
RPM is just frequency in cycles per minute instead of cycles per second. The formula is:
RPM = Hz × 60
| Frequency (Hz) | Speed (rpm) |
|---|---|
| 1 Hz | 60 rpm |
| 10 Hz | 600 rpm |
| 25 Hz | 1500 rpm |
| 50 Hz | 3000 rpm |
| 60 Hz | 3600 rpm |
| 100 Hz | 6000 rpm |
Why convert hertz to RPM?
Common reasons to convert Hz to rpm include:
- Relating mains frequency (50/60 Hz) to motor shaft speed.
- Checking whether a fan, pump or compressor is running at its rated speed.
- Converting sensor readings from frequency into a more intuitive rpm value.
- Comparing rotational speeds across different machines and drives.
