How the formula works
Both millihenry and henry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in millihenrys by 0.001 to get henrys. To reverse the conversion, multiply a henry value by 1000 to get back to millihenrys.
Frequently asked questions
What is Millihenry (mH)?
A Millihenry (mH) equals 1/1,000 henry(s), a scaled unit of inductance used for milli-scale electrical work.
What is Henry (H)?
The henry (H) is the SI unit of inductance, describing the voltage induced per unit rate of change of current.
How do I convert millihenrys to henrys?
Multiply the millihenry value by 0.001 to get the equivalent in henrys. For example, 5 mH × 0.001 = 0.005 H.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert henrys back to millihenrys?
Yes. Divide the henry value by 0.001, or multiply it by 1000, to get millihenrys.
