Frequency Converter
Fast, accurate frequency conversions, right in your browser.
The Frequency Converter converts frequency between common units — hertz, kilohertz, megahertz — instantly and accurately. Enter a value in one unit and see it converted to all supported units at once.
Whether you're working on an engineering calculation, a recipe, a science assignment or converting specs from an international source, this tool eliminates manual conversion-factor lookups and rounding errors.
How to Convert frequency
- Enter your value and select the starting unit
- Choose the unit you want to convert to
- The converted result appears instantly
Best Practices
- Double-check which unit variant is expected (e.g. US vs. metric) for your specific use case
- For engineering or scientific work, verify precision requirements against the tool's decimal output
- Bookmark this tool for quick repeated conversions
This tool is free to use with no signup required.
Frequently Asked Questions
What units does this frequency converter support?
Common units include hertz (Hz), kilohertz (kHz), megahertz (MHz), and gigahertz (GHz).
How many hertz are in a kilohertz?
1,000 hertz (Hz) equal one kilohertz (kHz).
What frequency does household AC power run at?
Most of the world uses either 50 Hz or 60 Hz for AC power — the US and parts of the Americas use 60 Hz, while Europe, Asia, and Africa mostly use 50 Hz.
Is this useful for audio or radio work?
Yes — audio frequencies (measured in Hz/kHz) and radio frequencies (measured in MHz/GHz) commonly need unit conversion when comparing equipment specifications.
Is this tool free to use?
Yes, completely free with no signup, no limits and no software to install.
Is my data saved anywhere?
No — conversions run in your browser and the values you enter are not stored or sent to a server.
What is the human hearing range in Hz?
Humans typically hear frequencies from about 20 Hz to 20,000 Hz (20 kHz), though this range narrows with age.
Is this useful for computer processor speed comparisons?
Yes — CPU clock speeds are measured in GHz, and this tool can help with related frequency unit conversions, though overall performance depends on more than clock speed alone.
What frequency does WiFi typically operate at?
Common WiFi bands operate at 2.4 GHz and 5 GHz, with newer standards also using 6 GHz.
How is frequency related to wavelength?
Frequency and wavelength are inversely related for waves traveling at a constant speed (like light or radio waves) — higher frequency means shorter wavelength, though converting between them requires knowing the wave's propagation speed, not just a unit conversion.
