How the formula works
Both femtofarad and farad measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtofarads by 1.000000e-15 to get farads. To reverse the conversion, multiply a farad value by 1.000000e+15 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 Farad (F)?
The farad (F) is the SI unit of capacitance, measuring a capacitor's ability to store electric charge per volt.
How do I convert femtofarads to farads?
Multiply the femtofarad value by 1.000000e-15 to get the equivalent in farads. For example, 5 fF × 1.000000e-15 = 5.000000e-15 F.
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 farads back to femtofarads?
Yes. Divide the farad value by 1.000000e-15, or multiply it by 1.000000e+15, to get femtofarads.
