Rendered to 6 significant figures.
Formula
Formula
mH = kH × 1000000
Multiply any value in kilohenries by 1000000 to obtain the value in millihenries.
Worked example
Convert 1 kH to mH.
- 01Start with 1 kH.
- 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 mH.
Result1 kH = 1.00000e+6 mH

FAQ
What is the conversion factor from kH to mH?
1 kH equals 1000000 mH. To convert, multiply the value in kilohenries by 1000000.
How do I convert 1 kH to mH?
1 kH = 1.00000e+6 mH. For any value, multiply by 1000000.
How do I convert mH back to kH?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 mH = 1e-6 kH.
When would I need to convert kilohenry to millihenry?
Inductance conversions between kH and mH are used in transformer and reactor design, EMI filter sizing, switched-mode power supply development and sensor coil specification. Henries cover power-inductor and choke ratings; millihenries through nanohenries cover signal-path filters and high-frequency electronics.
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).
