How the formula works
Both femtofarad and attofarad measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtofarads by 1000 to get attofarads. To reverse the conversion, multiply a attofarad value by 0.001 to get back to femtofarads.
Frequently asked questions
What is Femtofarad (fF)?
A Femtofarad (fF) equals 1e-15 farad(s), a scaled unit of capacitance used for femto-scale electrical work.
What is Attofarad (aF)?
An Attofarad (aF) equals 1e-18 farad(s), a scaled unit of capacitance used for atto-scale electrical work.
How do I convert femtofarads to attofarads?
Multiply the femtofarad value by 1000 to get the equivalent in attofarads. For example, 5 fF × 1000 = 5000 aF.
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 attofarads back to femtofarads?
Yes. Divide the attofarad value by 1000, or multiply it by 0.001, to get femtofarads.
