kHz = cycles/hr × 2.777778e-7
Multiply any value in cycles per hour by 2.777778e-7 to obtain the value in kilohertz.
Worked example
Convert 3.60000e+6 cycles/hr to kHz.
- 01Start with 3.60000e+6 cycles/hr.
- 02Multiply by the conversion factor: 3.60000e+6 × 2.777778e-7 = 1 kHz.
Result3.60000e+6 cycles/hr = 1 kHz

FAQ
What is the conversion factor from cycles/hr to kHz?
1 cycles/hr equals 2.777778e-7 kHz. To convert, multiply the value in cycles per hour by 2.777778e-7.
How do I convert 1 cycles/hr to kHz?
1 cycles/hr = 2.77778e-7 kHz. For any value, multiply by 2.777778e-7.
How do I convert kHz back to cycles/hr?
Divide by the same factor — or equivalently, multiply by 3600000. So 1 kHz = 3.60000e+6 cycles/hr.
When would I need to convert cycle per hour to kilohertz?
Frequency conversions between cycles/hr and kHz 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).
