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.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 µH = 0.001 mH
1 mH = 1000 µH
To convert microhenry to millihenry, multiply by 0.001.
To convert millihenry to microhenry, multiply by 1000.
Example: convert 10 µH to mH
10 × 0.001 = 0.01 mH
About these units
Short background on the units used in this conversion.
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.
Frequently asked questions
How many millihenrys are in one microhenry?
One microhenry equals 0.001 millihenrys. Multiply your microhenrys value by 0.001 to convert to millihenrys.
What is the conversion formula?
mH = µH × 0.001The reverse is
µH = mH × 1,000, using the same exact factors as this converter.Is this Microhenry to Millihenry converter private?
