How to convert millihenries to henries
H = mH × 0.001Multiply the value in millihenries by 0.001. To go the other way, multiply by 1,000 (or divide by 0.001).
A millihenry is smaller than a henry: it takes 1,000 millihenries to make one henry.

Frequently asked questions
How many henries are in one millihenry?
There are 0.001 henries in one millihenry, and this value is exact by definition.
How do I convert millihenries to henries?
Multiply the number of millihenries by 0.001. For example, 10 mH × 0.001 = 0.01 H.
How many millihenries are in one henry?
One henry equals 1,000 millihenries. That is the reverse factor, 1 ÷ 0.001.
What is 10 millihenries in henries?
10 mH = 0.01 H.
Is this mH to H converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
