About Millihenry (mH)
Metric submultiple of electrical inductance equal to one thousandth of a henry (10โปยณ H).
History: Standard unit for audio frequency crossovers and electric motor winding inductance.
Common Uses: Speaker crossover coils, relay coils, and solenoid actuators.
About Henry (H)
The SI unit of electrical inductance, defined as the inductance of a closed circuit in which an electromotive force of one volt is produced when the electric current in the circuit varies uniformly at the rate of one ampere per second (1 H = 1 Vยทs/A = 1 Wb/A).
History: Named in honor of Joseph Henry, American scientist who discovered electromagnetic self-induction independently of Faraday.
Common Uses: Large power transformers, electrical grid filter chokes, and motor windings.
โ Frequently Asked Questions
How many Henries are in 1 Millihenry?
There are exactly 0.001 Henries in 1 Millihenry (1 mH = 0.001 H).
What is the formula to convert Millihenry to Henry?
The formula is: Henry = Millihenry / 1000. Since 1 Henry = 1000 Millihenries, divide the value in Millihenries by 1000.
How do I convert 1 mH to H manually?
To convert 1 mH to H: apply the formula Henry = Millihenry / 1000. Substituting gives: 1 / 1000 = 0.001 H.
