Formula
Formula
rph = µHz × 0.0036
Multiply any value in microhertz by 0.0036 to obtain the value in revolutions per hour.
Worked example
Convert 3.60000e+6 µHz to rph.
- 01Start with 3.60000e+6 µHz.
- 02Multiply by the conversion factor: 3.60000e+6 × 0.0036 = 12960 rph.
Result3.60000e+6 µHz = 12960 rph

FAQ
What is the conversion factor from µHz to rph?
1 µHz equals 0.0036 rph. To convert, multiply the value in microhertz by 0.0036.
How do I convert 1 µHz to rph?
1 µHz = 0.0036 rph. For any value, multiply by 0.0036.
How do I convert rph back to µHz?
Divide by the same factor — or equivalently, multiply by 277.7778. So 1 rph = 277.778 µHz.
When would I need to convert microhertz to revolution per hour?
Frequency conversions between µHz and rph 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).
