How the formula works
Both attohenry and femtohenry measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attohenrys by 0.001 to get femtohenrys. To reverse the conversion, multiply a femtohenry value by 1000 to get back to attohenrys.
Frequently asked questions
What is Attohenry (aH)?
An Attohenry (aH) equals 1e-18 henry(s), a scaled unit of inductance used for atto-scale electrical work.
What is Femtohenry (fH)?
A Femtohenry (fH) equals 1e-15 henry(s), a scaled unit of inductance used for femto-scale electrical work.
How do I convert attohenrys to femtohenrys?
Multiply the attohenry value by 0.001 to get the equivalent in femtohenrys. For example, 5 aH × 0.001 = 0.005 fH.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert femtohenrys back to attohenrys?
Yes. Divide the femtohenry value by 0.001, or multiply it by 1000, to get attohenrys.
