About converting Megahertz to Gigahertz
Megahertz (MHz) and Gigahertz (GHz) are both units of frequency, so converting between them is a single multiplication: multiply your Megahertz figure by 0.001. Ten Megahertz comes to 0.01 Gigahertz, and a hundred works out at 0.1 Gigahertz.
Rule of thumb: going from Megahertz to Gigahertz divides, so the figure always shrinks — it takes about 1,000 Megahertz to make a single Gigahertz. If your answer came out bigger, 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 Gigahertz?
The gigahertz is where modern computing and wireless live. Processor clocks arrived in this range and have climbed very little since — chips got faster by adding cores and doing more work per cycle, not by ticking quicker — which is exactly why comparing two processors on gigahertz alone tells you very little. Wi-Fi is the other everyday gigahertz: the 2.4 GHz band travels further and through more walls, the 5 and 6 GHz bands carry more data over shorter distances, and that trade-off falls directly out of the frequency. Mobile networks are quoted the same way.
To put both in perspective: an FM station broadcasts at around 100 megahertz, while a laptop processor ticks at a few gigahertz.

Frequently asked questions
How many Gigahertz are in one Megahertz?
There are 0.001 Gigahertz in one Megahertz.
How do I convert Megahertz to Gigahertz?
Multiply the number of Megahertz by 0.001. For example, 10 Megahertz = 0.01 Gigahertz.
What is 100 Megahertz in Gigahertz?
100 Megahertz is equal to 0.1 Gigahertz.
How do I convert Gigahertz to Megahertz?
Multiply the Gigahertz value by 1,000 (or divide by 0.001).
Is this Megahertz to Gigahertz conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Megahertz = 0.001 Gigahertz is the complete value — nothing is rounded away.
