Formula
rps = mHz × 0.001
Multiply any value in millihertz by 0.001 to obtain the value in revolutions per second.
Worked example
Convert 1000 mHz to rps.
- 01Start with 1000 mHz.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 rps.
Result1000 mHz = 1 rps

FAQ
What is the conversion factor from mHz to rps?
1 mHz equals 0.001 rps. To convert, multiply the value in millihertz by 0.001.
How do I convert 1 mHz to rps?
1 mHz = 0.001 rps. For any value, multiply by 0.001.
How do I convert rps back to mHz?
Divide by the same factor — or equivalently, multiply by 1000. So 1 rps = 1000 mHz.
When would I need to convert millihertz to revolution per second?
Frequency conversions between mHz and rps 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).
