Frequency Converter
Convert between hertz, kilohertz, megahertz and gigahertz in one click.
The Frequency Converter is a free online tool that converts frequency values between hertz (Hz), kilohertz (kHz), megahertz (MHz) and gigahertz (GHz) instantly. No sign-up needed — enter a value, choose your units, and get an accurate result.
What is a frequency converter?
Frequency measures how many times an event repeats per second, and it's used across radio, audio, computing, and physics. Processor speeds are measured in GHz, radio stations in kHz or MHz, and basic wave calculations in Hz — this tool converts between them so you never have to shift decimal points by hand.
How to use the Frequency Converter
- Enter the frequency value you want to convert.

Frequently asked questions
Is the Frequency Converter free?
Yes, it's completely free with no sign-up required.
How many hertz are in a kilohertz?
One kilohertz equals 1,000 hertz, one megahertz equals 1,000,000 hertz, and one gigahertz equals 1,000,000,000 hertz.
How is frequency related to period?
Frequency and period are inversely related — period equals 1 divided by frequency, measured in seconds.
What uses gigahertz?
Computer processors, Wi-Fi bands, and high-frequency radar systems are commonly rated in gigahertz.
