How the formula works
Both femtohenry and henry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtohenrys by 1.000000e-15 to get henrys. To reverse the conversion, multiply a henry value by 1.000000e+15 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 Henry (H)?
The henry (H) is the SI unit of inductance, describing the voltage induced per unit rate of change of current.
How do I convert femtohenrys to henrys?
Multiply the femtohenry value by 1.000000e-15 to get the equivalent in henrys. For example, 5 fH × 1.000000e-15 = 5.000000e-15 H.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-15 is an exact, non-rounded value.
Can I convert henrys back to femtohenrys?
Yes. Divide the henry value by 1.000000e-15, or multiply it by 1.000000e+15, to get femtohenrys.
