About this tool
Frequency counts how often something repeats, measured in hertz (cycles per second). This converter links hertz and its multiples — used for radio, audio and processor speeds — with revolutions per minute, common for engines and rotating machinery.
The conversions are exact. Everything runs in your browser.
Frequently asked questions
What is one hertz?
One hertz is one cycle per second. A kilohertz is 1,000 Hz, a megahertz is a million, and a gigahertz is a billion.
How does RPM relate to hertz?
Revolutions per minute divided by 60 gives hertz, so 60 RPM equals 1 Hz.
