Frequency Converter
Convert frequency between millihertz, hertz, kilohertz, megahertz, gigahertz, and RPM, with every unit shown at once. Runs entirely in your browser.

Example shown — enter your own value. RPM assumes 1 revolution = 1 cycle.

How it works
- Enter a value and pick the units you're converting from and to.
- The result updates instantly, alongside every other unit in the table below.
- Use Swap to flip the two units, or Copy next to any row to grab just that value.
The formula
Hz = Value × (unit's Hz factor)
Result = Hz ÷ (target unit's Hz factor)
Example: 2.4 GHz to MHz is 2.4 × 1,000 = 2,400 MHz.
FAQ
How does RPM relate to Hertz?
RPM counts revolutions per minute, while Hertz counts cycles per second — since one revolution is one cycle, dividing RPM by 60 gives you Hertz (e.g. 3,600 RPM = 60 Hz), and multiplying Hz by 60 gives RPM.
What uses gigahertz values?
CPU clock speeds, Wi-Fi bands (2.4 GHz, 5 GHz), and radio frequencies are the most common places you'll see GHz — it represents billions of cycles per second.
Does anything I type get sent anywhere?
No. The conversion is a simple multiplication done locally in your browser — nothing is uploaded.
Why is a Hertz-based table used internally?
Every unit is defined by how many Hz it equals, so any conversion is just one multiply and one divide through that shared reference point, including the RPM-to-frequency conversion.
