About converting RPM to Megahertz
RPM (rpm) and Megahertz (MHz) are both units of frequency, so converting between them is a single multiplication: multiply your RPM figure by 0.00000001667. Ten RPM comes to 0.0000001667 Megahertz, and a hundred works out at 0.000001667 Megahertz.
Rule of thumb: going from RPM to Megahertz divides, so the figure always shrinks — it takes about 59,999,999.88 RPM to make a single Megahertz. If your answer came out bigger, you have the conversion the wrong way round.
What is a RPM?
RPM measures rotation rather than waves, but a revolution is a cycle like any other, which is what puts it in the same family as the hertz. It is the number on a car’s tachometer, where an engine idles low and a redline marks the point past which the valvetrain will not keep up. It rated hard drives for decades — 5,400 and 7,200 rpm were the two grades of consumer drive, and the faster platter genuinely meant quicker access, a distinction SSDs made irrelevant. It is also the spin-cycle figure on a washing machine, where more rpm means drier clothes and more noise.
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.
To put both in perspective: a car engine idles at around 800 rpm, while an FM station broadcasts at around 100 megahertz.

Frequently asked questions
How many Megahertz are in one RPM?
There are 0.00000001667 Megahertz in one RPM.
How do I convert RPM to Megahertz?
Multiply the number of RPM by 0.00000001667. For example, 10 RPM = 0.0000001667 Megahertz.
What is 100 RPM in Megahertz?
100 RPM is equal to 0.000001667 Megahertz.
How do I convert Megahertz to RPM?
Multiply the Megahertz value by 59,999,999.88 (or divide by 0.00000001667).
Is this RPM to Megahertz conversion exact?
The definition is exact — RPM and Megahertz are both fixed against the same base by international agreement — but the decimal shown here is rounded for readability, because the true ratio does not terminate. For engineering or scientific work, carry more decimal places than this page displays.
