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

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