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