Formula
Formula
MHz = rpm × 1.666667e-8
Multiply any value in revolutions per minute by 1.666667e-8 to obtain the value in megahertz.
Worked example
Convert 6e+7 rpm to MHz.
- 01Start with 6e+7 rpm.
- 02Multiply by the conversion factor: 6e+7 × 1.666667e-8 = 1 MHz.
Result6e+7 rpm = 1 MHz

FAQ
What is the conversion factor from rpm to MHz?
1 rpm equals 1.666667e-8 MHz. To convert, multiply the value in revolutions per minute by 1.666667e-8.
How do I convert 1 rpm to MHz?
1 rpm = 1.66667e-8 MHz. For any value, multiply by 1.666667e-8.
How do I convert MHz back to rpm?
Divide by the same factor — or equivalently, multiply by 6e+7. So 1 MHz = 6e+7 rpm.
When would I need to convert revolution per minute to megahertz?
Frequency conversions between rpm and MHz are needed in signal and RF engineering, motor and turbomachinery rotational-speed work, vibration and pulse-rate analysis, and control-loop sample-rate specification. Hz dominates electronics and instrumentation; kHz, MHz and GHz cover audio through microwave; rpm and rps dominate mechanical rotational equipment; cycles per minute, second and hour cover slow industrial cyclic processes. Angular frequency (rad/s) and time-period (Hz ↔ seconds) conversions are NOT included — they require either a 2π factor or a reciprocal relationship.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
