Formula
Formula
mHz = kHz × 1000000
Multiply any value in kilohertz by 1000000 to obtain the value in millihertz.
Worked example
Convert 1 kHz to mHz.
- 01Start with 1 kHz.
- 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 mHz.
Result1 kHz = 1.00000e+6 mHz

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