What is the Frequency Converter?
Convert any frequency unit to all others at once — Hz, kHz, MHz, GHz, rpm. Frequency conversions apply to radio, audio, processors, motors and electrical systems. Every conversion uses the exact internationally defined factor, so results are precise to 12 significant digits.
How to use the Frequency Converter
- Enter your value, your from unit.
- Results update automatically as you type; you can also press Calculate.
- Read the output: hertz (hz), kilohertz (khz), megahertz (mhz), gigahertz (ghz).
- Check the chart to see how the conversion scales.
Formula and method
Worked example
With value = 1, from unit = Hertz (Hz), the Frequency Converter returns hertz (hz): 1 Hz; kilohertz (khz): 0.001 kHz; megahertz (mhz): 0.000001 MHz.
Tips for better results
- Double-check which system a unit belongs to (for example US vs UK gallons).
- Use the swap button to convert in the opposite direction instantly.
- Bookmark the conversions you use most — each pair has its own page.
Frequently asked questions
What does the Frequency Converter do?
Convert any frequency unit to all others at once — Hz, kHz, MHz, GHz, rpm.
How is it calculated?
The Frequency Converter uses this method: value in target = value × (factor of source ÷ factor of target).
Can you show an example?
With value = 1, from unit = Hertz (Hz), the Frequency Converter returns hertz (hz): 1 Hz; kilohertz (khz): 0.001 kHz; megahertz (mhz): 0.000001 MHz.
Is the Frequency Converter accurate?
Yes. It uses standard formulas and exact constants, and the results are verified by our automated test suite. Values are displayed to up to 12 significant digits.
Is this tool free and private?
Yes — the Frequency Converter is completely free with no sign-up, and it runs entirely in your browser, so the values you enter are never uploaded to our servers.
