Formula

rpm = Hz × 60

Example

Example: convert 440 hertz to revolutions per minute.

440 Hz = 26400 rpm

Conversion table

hertz (Hz) revolutions per minute (rpm)
1 Hz 60 rpm
2 Hz 120 rpm
5 Hz 300 rpm
10 Hz 600 rpm
20 Hz 1200 rpm
50 Hz 3000 rpm
100 Hz 6000 rpm

Explanation

These are both units.

How to convert hertz to revolutions per minute

  1. Start with the value in hertz (Hz).
  2. Multiply it by 60.
  3. The result is the measurement in revolutions per minute (rpm).

Example: 440 Hz → 26400 rpm

Frequently Asked Questions

How do you convert Hz to kHz?

Divide hertz by 1,000 to get kilohertz.

How do you convert MHz to Hz?

Multiply megahertz by 1,000,000 to get hertz.

What is the difference between Hz and rpm?

Hz is cycles per second, while rpm is revolutions per minute.

How do you convert rpm to Hz?

Divide rpm by 60 to get hertz (Hz).

What frequency units can I convert here?

This converter supports Hz, kHz, MHz, GHz, THz, and rpm.

What does GHz mean?

GHz means gigahertz, or billions of cycles per second.

Is frequency used for sound and radio?

Yes. Frequency is used for audio, radio, electronics, and rotation rates.

Can frequency be written as 1/s?

Yes. A hertz is equivalent to one per second (s⁻¹).

How many rpm are in 1 Hz?

1 Hz equals 60 rpm because 1 cycle per second is 60 cycles per minute.

What is 60 Hz used for?

60 Hz is a common mains electricity frequency in some countries (others use 50 Hz).
