How to convert inductance
Inductance is measured in henries. Coils and chokes in circuits are usually millihenries, microhenries or nanohenries.
Every inductance unit is a fixed multiple of one base unit, the H. To convert a value, multiply it by the size of the starting unit and divide by the size of the target unit. For example, to convert mH to µH, multiply by 1. To go the other way, divide by 1.
The converter above does this for you and shows the exact formula under the result.

Frequently asked questions
How many µH is 1 mH?
One millihenry (mH) is 1,000 microhenries (µH).
How do I convert mH to µH?
Multiply the value in mH by 1 to get µH. For example, 10 mH = 1 µH.
How many µH is 1 mH?
1 mH = 1 µH, and 1 µH = 0.001 mH.
