Convert RPM to Megahertz (rpm to MHz)
1 revolution per minute (rpm) = 1.666666667 × 10⁻⁸ megahertz (MHz). 1 MHz = 60000000 rpm. Example: 15 rpm = 15 × 1.666666667 × 10⁻⁸ = 2.5 × 10⁻⁷ MHz.

How to Convert RPM to Megahertz
- 1 rpm = 1.666666667 × 10⁻⁸ MHz
- 1 MHz = 60000000 rpm
- Example: convert 15 rpm to MHz: 15 rpm = 15 × 1.666666667 × 10⁻⁸ MHz = 2.5 × 10⁻⁷ MHz
Formula
MHz = rpm × 1.666666666667 × 10⁻⁸
or MHz = rpm ÷ 60000000
Derivation from SI units:
- 1 rpm = 1/60 revolution per second = 1/60 Hz.
- 1 MHz = 10⁶ Hz.
- 1 rpm = 0.01666666666667 Hz ÷ 1000000 Hz per MHz = 1.666666666667 × 10⁻⁸ MHz
Both units are defined exactly, so the factor is exact. RPM definition: revolution per minute; Megahertz definition: megahertz.
Worked examples
- A reading of 750 rpm converts to 0.0000125 MHz.
750 rpm × 1.666666667 × 10⁻⁸ = 0.0000125 MHz - A value of 1500 rpm is 0.000025 MHz.
1500 rpm × 1.666666667 × 10⁻⁸ = 0.000025 MHz

Frequently asked questions
How many megahertz are in 1 revolution per minute?
1 rpm = 1.666666667 × 10⁻⁸ MHz.
How do I convert revolutions per minute to megahertz?
Multiply the value in rpm by 1.666666667 × 10⁻⁸, or divide it by 60000000. For example, 15 rpm × 1.666666667 × 10⁻⁸ = 2.5 × 10⁻⁷ MHz.
Is the rpm to MHz conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
