The hertz
The hertz (Hz) is the SI derived unit of frequency, equal to one cycle per second. It is the universal unit for sound pitch, electrical AC frequency, processor clock speed (in multiples), and radio and wireless signal frequencies.
Hertz to Revolutions per minute Converter
1 Hz = 60 rpm (hertz → revolution per minute)
1 Hz = 60 rpm
1 hertz equals 60 revolutions per minute. To convert hertz to revolutions per minute, multiply the hertz value by 60. For quick reference: 1 Hz = 60 rpm, 5 Hz = 300 rpm, 10 Hz = 600 rpm, 100 Hz = 6000 rpm.
Formula
Revolutions per minute = Hertz × 60Quick

Real-world reference
Standard mains electricity in most of the world is 50 or 60 Hz. Human hearing spans roughly 20 Hz to 20,000 Hz. In revolutions per minute, that gives you: 1 Hz = 60 rpm, 10 Hz = 600 rpm, 100 Hz = 6000 rpm.
Frequently asked questions
- How many revolutions per minute are in 1 hertz?
- 1 hertz equals 60 revolutions per minute.
- How do I convert hertz to revolutions per minute?
- Multiply the hertz value by 60. So x Hz × 60 = the equivalent in rpm.
- What is 5 hertz in revolutions per minute?
- 5 hertz equals 300 revolutions per minute.
- What is 10 hertz in revolutions per minute?
- 10 hertz equals 600 revolutions per minute.
- What is 100 hertz in revolutions per minute?
- 100 hertz equals 6000 revolutions per minute.
- How do I convert back from revolutions per minute to hertz?
- Multiply the revolution per minute value by 0.0166667. For example, 1 rpm = 0.0166667 Hz.
- Is the hertz bigger than the revolution per minute?
- Yes. 1 hertz is larger than 1 revolution per minute — specifically 60 times larger.
- Are these conversion factors exact?
- The factor is derived directly from the SI definitions of hertz and revolution per minute; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.
About the hertz and the revolution per minute
The revolution per minute
Revolutions per minute (RPM) equals 1/60 Hz — one full rotation every 60 seconds' worth of a cycle. It is the standard unit for engine, motor, and turntable rotational speed in mechanical and automotive engineering.
