Frequency Converter
Converts frequency between electronic units and revolutions per minute. One hertz is one cycle per second, so 60 RPM is exactly 1 Hz.

The formula
result = value × (from factor ÷ to factor)
Each frequency unit is defined by its size relative to the hertz, so converting between any two is a single multiplication.
Every frequency unit
| Unit | Symbol | In one hertz |
|---|---|---|
| hertz | Hz | 1 |
| kilohertz | kHz | 0.001 |
| megahertz | MHz | 0.000001 |
| gigahertz | GHz | 0.000000001 |
| revolution per minute | rpm | 60 |
Frequently Asked Questions
How do I convert RPM to hertz?
Divide by 60. An engine at 3,000 RPM is turning at 50 Hz.
What frequency is mains electricity?
50 Hz across most of the world, 60 Hz in North America and parts of Japan and South America.
How does frequency relate to wavelength?
Wavelength = wave speed ÷ frequency. For radio in air, that is roughly 300 ÷ frequency in MHz, giving metres — so 100 MHz FM has a 3 m wavelength.
