Convert Hertz to RPM (Hz to rpm)
1 hertz (Hz) = 60 revolutions per minute (rpm). 1 rpm = 0.01666666667 Hz. Example: 50 Hz = 50 × 60 = 3000 rpm.

How to Convert Hertz to RPM
- 1 Hz = 60 rpm
- 1 rpm = 0.01666666667 Hz
- Example: convert 50 Hz to rpm: 50 Hz = 50 × 60 rpm = 3000 rpm
Formula
rpm = Hz × 60
Derivation from SI units:
- 1 Hz = 1 s⁻¹, one cycle per second.
- 1 rpm = 1/60 revolution per second = 1/60 Hz.
Both units are defined exactly, so the factor is exact. Hertz definition: hertz; RPM definition: revolution per minute.
Worked examples
- A synchronous speed of 50 Hz is 3000 rpm.
50 Hz × 60 = 3000 rpm - A shaft frequency of 25 Hz is 1500 rpm.
25 Hz × 60 = 1500 rpm

Where it's used
Frequencies in hertz from drives, sensors and spectrum analysers are converted to rpm to read them as rotational speeds of motors, fans and spindles. Multiply by 60.

Frequently asked questions
What rpm does a VFD give at 50 Hz?
Multiply drive frequency by 120 and divide by the poles: a 4-pole motor runs near 1500 rpm at 50 Hz and 750 rpm at 25 Hz, less slip.
How many revolutions per minute are in 1 hertz?
1 Hz = 60 rpm.
How do I convert hertz to revolutions per minute?
Multiply the value in Hz by 60. For example, 50 Hz × 60 = 3000 rpm.
Is the Hz to rpm conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
