Worked example
Convert 3600 cycles/hr to rpm.
- 01Start with 3600 cycles/hr.
- 02Multiply by the conversion factor: 3600 × 0.01666667 = 60 rpm.
Result3600 cycles/hr = 60 rpm

FAQ
What is the conversion factor from cycles/hr to rpm?
1 cycles/hr equals 0.01666667 rpm. To convert, multiply the value in cycles per hour by 0.01666667.
How do I convert 1 cycles/hr to rpm?
1 cycles/hr = 0.0166667 rpm. For any value, multiply by 0.01666667.
How do I convert rpm back to cycles/hr?
Divide by the same factor — or equivalently, multiply by 60. So 1 rpm = 60 cycles/hr.
When would I need to convert cycle per hour to revolution per minute?
Frequency conversions between cycles/hr and rpm 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).
