What is a millihenry?

A millihenry (mH) is a derived SI unit of electrical inductance equal to 10^-3 henry, representing the ability of an element to generate voltage opposing current changes.

What applications use femtohenry units?

Femtohenry units are used to specify very small inductances such as parasitic inductance in PCB traces, on-chip inductors, and components in high-frequency circuit designs.

How do I convert millihenry to femtohenry?

Multiply the millihenry value by 1,000,000,000,000 to obtain the equivalent femtohenry value.
