Rendered to 6 significant figures.
Formula
Formula
kHz = mHz × 1e-6
Multiply any value in millihertz by 1e-6 to obtain the value in kilohertz.
Worked example
Convert 1.00000e+6 mHz to kHz.
- 01Start with 1.00000e+6 mHz.
- 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 kHz.
Result1.00000e+6 mHz = 1 kHz

FAQ
What is the conversion factor from mHz to kHz?
1 mHz equals 1e-6 kHz. To convert, multiply the value in millihertz by 1e-6.
How do I convert 1 mHz to kHz?
1 mHz = 1e-6 kHz. For any value, multiply by 1e-6.
How do I convert kHz back to mHz?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 kHz = 1.00000e+6 mHz.
When would I need to convert millihertz to kilohertz?
Frequency conversions between mHz 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).
