How the formula works
Both femtohenry and attohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtohenrys by 1000 to get attohenrys. To reverse the conversion, multiply a attohenry value by 0.001 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 Attohenry (aH)?
An Attohenry (aH) equals 1e-18 henry(s), a scaled unit of inductance used for atto-scale electrical work.
How do I convert femtohenrys to attohenrys?
Multiply the femtohenry value by 1000 to get the equivalent in attohenrys. For example, 5 fH × 1000 = 5000 aH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert attohenrys back to femtohenrys?
Yes. Divide the attohenry value by 1000, or multiply it by 0.001, to get femtohenrys.
