Frequently Asked Questions

How many hertz are in a megahertz?

There are 1,000,000 hertz in one megahertz. To convert megahertz to hertz multiply by one million; to go the other way divide by one million.

How do I convert MHz to GHz?

Divide the megahertz by 1000, since one gigahertz equals 1000 megahertz. For example, 2400 MHz is 2.4 GHz.

What is rpm in this tool?

Revolutions per minute measures how many full turns happen each minute. One rpm equals one sixtieth of a hertz, so 60 rpm is 1 Hz.

What is hertz used for?

Hertz measures how many times something repeats per second, from sound waves and radio signals to processor and screen refresh rates.

Is my data sent anywhere?

No. The conversion runs entirely in your browser, so the values you enter never leave your computer and it works offline once loaded.

Can I see all frequency units at once?

Yes. The table converts your value into every frequency unit at the same time, from hertz up to gigahertz.
