Convert henry to millihenry

Henry

The henry (symbol: H) is the SI unit of electrical inductance. A circuit has an inductance of one henry when an electromotive force of one volt is induced by a current changing at a rate of one ampere per second. Named after Joseph Henry, who independently discovered electromagnetic induction.

Millihenry

The millihenry (symbol: mH) is equal to 10⁻³ henries. It is the most common unit for practical inductors used in power supplies, RF filters, and audio crossover networks.
