Millihenry (mH)
The millihenry (mH) equals 0.001 henry — common for power inductors, chokes, and larger wound components.
Millihenries label power-supply inductors, filter chokes, and audio crossover coils.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 mH = 1000 µH
1 µH = 0.001 mH
To convert millihenry to microhenry, multiply by 1000.
To convert microhenry to millihenry, multiply by 0.001.
Example: convert 10 mH to µH
10 × 1000 = 10000 µH
About these units
Short background on the units used in this conversion.
Microhenry (µH)
The microhenry (µH) equals 10⁻⁶ henry — the everyday unit for RF chokes, buck-converter inductors, and SMD parts.
Microhenries appear on switch-mode power supply inductors, RF coils, and ferrite bead specifications.
Frequently asked questions
How many microhenrys are in one millihenry?
One millihenry equals 1,000 microhenrys. Multiply your millihenrys value by 1,000 to convert to microhenrys.
What is the conversion formula?
µH = mH × 1,000The reverse is
mH = µH × 0.001, using the same exact factors as this converter.Is this Millihenry to Microhenry converter private?
