Millihenry to Henry Converter
1 Millihenry equals 0.001 Henries (H). Inductance is measured in henries (H). Most practical inductors used in electronics — from power supplies to RF filters — are in the millihenry (mH) or microhenry (µH) range. Use the converter below to change any millihenries value into henries instantly.

Frequently asked questions
How many Henries are in a Millihenry?
1 Millihenry equals 0.001 Henries.
How do you convert Millihenries to Henries?
Use the formula: Henry = Millihenry × 0.001. For example, 10 Millihenries equals 0.01 Henries.
What is 1 Millihenry in Henries?
1 Millihenry (mH) is equal to 0.001 Henries (H).
What is a henry?
The henry (H) is the SI unit of inductance. A coil has an inductance of one henry when a current change of one ampere per second induces an electromotive force of one volt. It is named after Joseph Henry, who independently discovered electromagnetic induction alongside Michael Faraday.
What inductance values are typical in electronics?
Power supply inductors: 1 µH – 10 mH. RF chokes and filters: 10 nH – 100 µH. Audio transformers: 1 mH – several henries. Motor windings and power transformers: 10 mH – several henries. Microhenry values (µH) are standard in switch-mode power supplies (SMPS).
