How to Convert Henries to Millihenries

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

millihenries = henries × 1,000

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

For example, here's how to convert 5 henries to millihenries using the formula above.
5 H = (5 × 1,000) = 5,000 mH

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

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.

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 NIST recommends using "henries" as the plural form of the unit, however the usage of "henrys" is also common.

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.
