How the formula works
Both femtohenry and millihenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtohenrys by 1.000000e-12 to get millihenrys. To reverse the conversion, multiply a millihenry value by 1.000000e+12 to get back to femtohenrys.
Frequently asked questions
What is Femtohenry (fH)?
A Femtohenry (fH) equals 1e-15 henry(s), a scaled unit of inductance used for femto-scale electrical work.
What is Millihenry (mH)?
A Millihenry (mH) equals 1/1,000 henry(s), a scaled unit of inductance used for milli-scale electrical work.
How do I convert femtohenrys to millihenrys?
Multiply the femtohenry value by 1.000000e-12 to get the equivalent in millihenrys. For example, 5 fH × 1.000000e-12 = 5.000000e-12 mH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-12 is an exact, non-rounded value.
Can I convert millihenrys back to femtohenrys?
Yes. Divide the millihenry value by 1.000000e-12, or multiply it by 1.000000e+12, to get femtohenrys.
