How the formula works
Both attofarad and femtofarad measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attofarads by 0.001 to get femtofarads. To reverse the conversion, multiply a femtofarad value by 1000 to get back to attofarads.
Frequently asked questions
What is Attofarad (aF)?
An Attofarad (aF) equals 1e-18 farad(s), a scaled unit of capacitance used for atto-scale electrical work.
What is Femtofarad (fF)?
A Femtofarad (fF) equals 1e-15 farad(s), a scaled unit of capacitance used for femto-scale electrical work.
How do I convert attofarads to femtofarads?
Multiply the attofarad value by 0.001 to get the equivalent in femtofarads. For example, 5 aF × 0.001 = 0.005 fF.
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 femtofarads back to attofarads?
Yes. Divide the femtofarad value by 0.001, or multiply it by 1000, to get attofarads.
