Frequency Converter
Convert frequency between hertz, kilohertz, megahertz, gigahertz, and RPM.
How it works
Frequency counts how many times something repeats per second, measured in hertz. Radios, processors, and networks pile on the prefixes — kilo, mega, giga — which are just steps of a thousand.
Mechanical rotation is often quoted in revolutions per minute instead, and since a minute has 60 seconds, one hertz equals 60 RPM. The tool bridges the electronic and mechanical worlds in one place.
Enter a value in any unit and the others update immediately, whether you are reading a CPU spec in gigahertz or an engine speed in RPM.
Frequently asked questions
How do I use this converter?
Enter a value and choose the unit you are starting from. The tool instantly shows the equivalent in every other frequency unit, so there is nothing to submit.
Are the conversions exact?
They use standard published conversion factors, so they are accurate for everyday and technical use. Results are rounded for readability, not because the math is approximate.
Can I convert in either direction?
Yes. Pick any unit as your starting point and read off the others — the conversion works both ways.
