Formula

Formula
μH = mH × 1000

Multiply any value in millihenries by 1000 to obtain the value in microhenries.

Worked example

Convert 1 mH to μH.

  1. 01Start with 1 mH.
  2. 02Multiply by the conversion factor: 1 × 1000 = 1000 μH.
Result1 mH = 1000 μH

FAQ

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