Formula

Formula
cycles/min = rph × 0.01666667

Multiply any value in revolutions per hour by 0.01666667 to obtain the value in cycles per minute.

Worked example

Convert 60 rph to cycles/min.

  1. 01Start with 60 rph.
  2. 02Multiply by the conversion factor: 60 × 0.01666667 = 1 cycles/min.
Result60 rph = 1 cycles/min

FAQ

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