Formula

Formula
cycles/s = rph × 0.0002777778

Multiply any value in revolutions per hour by 0.0002777778 to obtain the value in cycles per second.

Worked example

Convert 3600 rph to cycles/s.

  1. 01Start with 3600 rph.
  2. 02Multiply by the conversion factor: 3600 × 0.0002777778 = 1 cycles/s.
Result3600 rph = 1 cycles/s

FAQ

What is the conversion factor from rph to cycles/s?
1 rph equals 0.0002777778 cycles/s. To convert, multiply the value in revolutions per hour by 0.0002777778.
How do I convert 1 rph to cycles/s?
1 rph = 0.000277778 cycles/s. For any value, multiply by 0.0002777778.
How do I convert cycles/s back to rph?
Divide by the same factor — or equivalently, multiply by 3600. So 1 cycles/s = 3600 rph.
When would I need to convert revolution per hour to cycle per second?
Frequency conversions between rph and cycles/s 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).
