FAQ
What is the conversion factor from rpm to µHz?
1 rpm equals 16666.67 µHz. To convert, multiply the value in revolutions per minute by 16666.67.
How do I convert 1 rpm to µHz?
1 rpm = 16666.7 µHz. For any value, multiply by 16666.67.
How do I convert µHz back to rpm?
Divide by the same factor — or equivalently, multiply by 6e-5. So 1 µHz = 6e-5 rpm.
When would I need to convert revolution per minute to microhertz?
Frequency conversions between rpm and µHz 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).
