Fill in the values and the answer updates as you type.
How the Frequency Converter works
1 Hz is one cycle per second. 1 kHz = 1,000 Hz, 1 MHz = 1,000,000 Hz, and 1 RPM = 1/60 Hz. The period is the time of one cycle, 1 ÷ frequency. Example: with the default values, hertz (hz) comes to 2,400,000,000.
Inputs and results
The Frequency Converter takes 2 inputs and gives 6 results.
What you enter
- Value — starts at 2.4.
- From — starts at Gigahertz (GHz). Choose from: Hertz (Hz), Kilohertz (kHz), Megahertz (MHz), Gigahertz (GHz) and Revolutions per minute (RPM).
What you get
- Hertz (Hz)
- Kilohertz (kHz)
- Megahertz (MHz)
- Gigahertz (GHz)
- Revolutions per minute (RPM)
- Period of one cycle
Example: Frequency Converter with the starting values
With value 2.4 and from Gigahertz (GHz), the calculator returns:
| Hertz (Hz) | 2,400,000,000 |
|---|---|
| Kilohertz (kHz) | 2,400,000 |
| Megahertz (MHz) | 2,400 |
| Gigahertz (GHz) | 2.4 |
| Revolutions per minute (RPM) | 144,000,000,000 |
| Period of one cycle | 4.167e-10 s |
Change any value above and the results update straight away.
Frequency Converter FAQ
How do I use the Frequency Converter?
Enter value and from in the fields, then read hertz (hz), kilohertz (khz), megahertz (mhz) and gigahertz (ghz) in the result panel. The answer updates as you type, and you can press Calculate or Enter to refresh it. Use “Copy link” to share your exact numbers with someone else.
What does the Frequency Converter calculate?
Convert hertz, kilohertz, megahertz, gigahertz, and RPM. It returns hertz (hz), kilohertz (khz), megahertz (mhz) and gigahertz (ghz) from the 2 values you provide.
What values does the Frequency Converter start with?
It opens with value 2.4 and from Gigahertz (GHz) so you can see a working result straight away. Replace them with your own numbers, or press Reset to return to these starting values.
Is the Frequency Converter free and private?
Yes. It is free, needs no account, and runs in your browser, so nothing you type is sent to or stored on our servers. See the Privacy Policy for details.
Can I rely on the Frequency Converter for important decisions?
Treat the result as a well-rounded estimate. Real situations often have details a general calculator cannot know, so confirm important decisions with a qualified professional. See the Disclaimer for more.
