Revolutions per minute to hertz
Type a value in rpm to get it in Hz instantly.
That's 1.39× as fast as a resting heartbeat, while a car engine idling is 8× faster. As sound in air, one wave would be 205.8 m long.
Convert the other way: Hz to rpm
What it means
What does that look like?
The wavelength shown is for sound in air at 20 °C (343 m/s). Radio waves travel at the speed of light, so their wavelengths are far longer.
The math
How to convert rpm to Hz
To convert revolutions per minute to hertz, multiply by 0.0166667.
Example: 100 rpm × 0.0166667 = 1.66667 Hz.
In the other direction, 1 Hz = 60 rpm.

About these units
Revolutions per minute (rpm)
Revolutions per minute count full turns each minute: 60 rpm is 1 Hz. Engines, drills and hard drives are rated in rpm.
Hertz (Hz)
One hertz is one cycle per second. It is the SI unit of frequency and the base for every multiple below.
