Formula
Formula
mH = μH × 0.001
Multiply any value in microhenries by 0.001 to obtain the value in millihenries.
Worked example
Convert 1000 μH to mH.
- 01Start with 1000 μH.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 mH.
Result1000 μH = 1 mH

FAQ
What is the conversion factor from μH to mH?
1 μH equals 0.001 mH. To convert, multiply the value in microhenries by 0.001.
How do I convert 1 μH to mH?
1 μH = 0.001 mH. For any value, multiply by 0.001.
How do I convert mH back to μH?
Divide by the same factor — or equivalently, multiply by 1000. So 1 mH = 1000 μH.
When would I need to convert microhenry to millihenry?
Inductance conversions between μH 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?
Yes. Both μH and mH are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
