How to Convert Millihenries to Henries

conversion scale showing millihenries and equivalent henries electrical inductance values

To convert a millihenry measurement to a henry measurement, divide the electrical inductance by the conversion ratio. One henry is equal to 1,000 millihenries, so use this simple formula to convert:

henries = millihenries ÷ 1,000

The electrical inductance in henries is equal to the millihenries divided by 1,000.

For example, here's how to convert 5,000 millihenries to henries using the formula above.

5,000 mH = (5,000 ÷ 1,000) = 5 H

Millihenries and henries are both units used to measure electrical inductance. Keep reading to learn more about each unit of measure.

Millihenries

One millihenry is equal to 1/1,000 of a henry, which is the inductance of a conductor with one volt of electromotive force when the current is increased by one ampere per second.

The millihenry is a multiple of the henry, which is the SI derived unit for electrical inductance. In the metric system, "milli" is the prefix for 10^-3. Millihenries can be abbreviated as mH, for example 1 millihenry can be written as 1 mH.

Henries

One henry is equal to the inductance of a conductor in which there is one volt of electromotive force when the current through the conductor is increased by one ampere per second.^[1]

The henry is the SI derived unit for electrical inductance in the metric system. Henries can be abbreviated as H, for example 1 henry can be written as 1 H.

The National Institute of Standards and Technology recommends using "henries" as the plural form of the unit, however the usage of "henrys" is also common.^[2]
