Convert Revolutions per minute to Megahertz
1 revolution per minute is 1.67e-8 MHz. One revolution per minute is exactly 1.66666666667e-8 megahertz.
One revolution per minute is 1.6667 × 10^-8 megahertz. To convert revolutions per minute to megahertz, multiply by 1.6667 × 10^-8; to go the other way, divide by 1.6667 × 10^-8 or multiply by 60000000. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Special Publication 811. One turn a minute, so 60 rpm is 1 Hz.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert revolutions per minute to megahertz? The converter and the working
- 1.Take the measurement in revolutions per minute.
- 2.Multiply by 1.6667 × 10^-8 — that is how many megahertz fit in one revolution per minute.
- 3.To go back the other way, divide by 1.6667 × 10^-8, or multiply by 60000000.
Worked example: 25 revolutions per minute to megahertz
- Formula
- rpm × 1.6667 × 10^-8 = MHz
- Arithmetic
- 25 × 1.6667 × 10^-8 = 4.17e-7 MHz
- Answer
- 25 rpm = 4.17e-7 MHz
The factor is rounded for display; the figure above is computed from the full value.

What is a revolution per minute?
One turn a minute, so 60 rpm is 1 Hz. Engines, drills and hard drives are all rated in it: a 7,200 rpm drive spins at 120 Hz.
What is a megahertz?
A million hertz. FM radio sits at 88 to 108 MHz, and a processor clock was quoted here until the late 1990s.
How many megahertz are in a revolution per minute?
One revolution per minute is 1.6667 × 10^-8 megahertz. Going the other way, one megahertz is 60000000 revolutions per minute. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.

The whole group — 6 units with their symbols and the size of each one in hertzs — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a revolution per minute.
