Frequency Converter (Hz, kHz, MHz, GHz, RPM)
Convert a frequency between hertz-based units (Hz, kHz, MHz, GHz) and revolutions per minute (RPM), used for motor and engine speed. Runs entirely in your browser.
How it works
Every unit is converted through a common base unit — the hertz (one cycle per second). RPM measures rotations per minute, so 1 Hz (one rotation per second) equals exactly 60 RPM.
Common conversions
| From | To | Result |
|---|---|---|
| 1 Hz | RPM | 60 RPM |
| 3000 RPM | Hz | 50 Hz |
| 2.4 GHz | MHz | 2400 MHz (Wi-Fi band) |
| 60 Hz | RPM | 3600 RPM (mains-synchronous motor speed) |
FAQ
How many RPM is 1 Hz?
Exactly 60 RPM — 1 hertz is one cycle per second, and there are 60 seconds in a minute.
Why does a CPU's GHz matter?
Clock frequency (in GHz) is cycles per second, not by itself a measure of total performance — architecture, core count, and instructions-per-cycle also matter, but frequency is one input to comparing chips generation over generation.
