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.
Revolutions per minute to Hertz Converter
1 rpm = 0.0166667 Hz (revolution per minute → hertz)
1 rpm = 0.0166667 Hz
1 revolution per minute equals 0.0166667 hertz. To convert revolutions per minute to hertz, multiply the revolution per minute value by 0.0166667. For quick reference: 1 rpm = 0.0166667 Hz, 5 rpm = 0.0833333 Hz, 10 rpm = 0.166667 Hz, 100 rpm = 1.66667 Hz.
Formula
Hertz = Revolutions per minute × 0.0166667Quick

Real-world reference
A car engine idles at around 600–1,000 RPM. A standard vinyl record turntable spins at 33⅓ or 45 RPM. In hertz, that gives you: 1 rpm = 0.0166667 Hz, 10 rpm = 0.166667 Hz, 100 rpm = 1.66667 Hz.
Frequently asked questions
- How many hertz are in 1 revolution per minute?
- 1 revolution per minute equals 0.0166667 hertz.
- How do I convert revolutions per minute to hertz?
- Multiply the revolution per minute value by 0.0166667. So x rpm × 0.0166667 = the equivalent in Hz.
- What is 5 revolutions per minute in hertz?
- 5 revolutions per minute equals 0.0833333 hertz.
- What is 10 revolutions per minute in hertz?
- 10 revolutions per minute equals 0.166667 hertz.
- What is 100 revolutions per minute in hertz?
- 100 revolutions per minute equals 1.66667 hertz.
- How do I convert back from hertz to revolutions per minute?
- Multiply the hertz value by 60. For example, 1 Hz = 60 rpm.

About the revolution per minute and the hertz
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.
