About converting Megahertz to Hertz
Megahertz (MHz) and Hertz (Hz) are both units of frequency, so converting between them is a single multiplication: multiply your Megahertz figure by 1,000,000. Ten Megahertz comes to 10,000,000 Hertz, and a hundred works out at 100,000,000 Hertz.
Rule of thumb: going from Megahertz to Hertz multiplies, so the figure always grows — one Megahertz is already 1,000,000 Hertz. If your answer came out smaller, you have the conversion the wrong way round.
What is a Megahertz?
The megahertz covers FM radio — the two-digit numbers on an FM dial are megahertz — along with broadcast television, walkie-talkies and a great deal of the spectrum in between. It is also the unit that once sold computers: through the 1980s and 1990s a processor’s megahertz figure was the headline specification, and buyers treated it as a direct measure of speed. That was always shaky, because how much work a chip does per cycle varies enormously between designs, and the assumption became known as the megahertz myth once rival architectures started beating faster-clocked ones.
What is a Hertz?
The hertz is one cycle per second — nothing more. It is named after Heinrich Hertz, who demonstrated experimentally that electromagnetic waves exist, confirming what until then had been theory. The unit itself is younger than it looks: engineers said "cycles per second", abbreviated cps, until hertz was formally adopted in 1960. Its reach is remarkable for so plain a definition. Mains electricity alternates at 50 or 60 Hz, human hearing starts at roughly 20 Hz, and a monitor advertised at 144 Hz is simply redrawing itself 144 times a second. Anything that repeats can be counted in hertz.
To put both in perspective: an FM station broadcasts at around 100 megahertz, while a screen refreshing 60 times a second runs at 60 hertz.

Frequently asked questions
How many Hertz are in one Megahertz?
There are 1,000,000 Hertz in one Megahertz.
How do I convert Megahertz to Hertz?
Multiply the number of Megahertz by 1,000,000. For example, 10 Megahertz = 10,000,000 Hertz.
What is 100 Megahertz in Hertz?
100 Megahertz is equal to 100,000,000 Hertz.
How do I convert Hertz to Megahertz?
Multiply the Hertz value by 0.000001 (or divide by 1,000,000).
Is this Megahertz to Hertz conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Megahertz = 1,000,000 Hertz is the complete value — nothing is rounded away.
