How the formula works
Both kilofarad and femtofarad measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kilofarads by 1.000000e+18 to get femtofarads. To reverse the conversion, multiply a femtofarad value by 1.000000e-18 to get back to kilofarads.
Frequently asked questions
What is Kilofarad (kF)?
A Kilofarad (kF) equals 1,000 farad(s), a scaled unit of capacitance used for kilo-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 kilofarads to femtofarads?
Multiply the kilofarad value by 1.000000e+18 to get the equivalent in femtofarads. For example, 5 kF × 1.000000e+18 = 5.000000e+18 fF.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+18 is an exact, non-rounded value.
Can I convert femtofarads back to kilofarads?
Yes. Divide the femtofarad value by 1.000000e+18, or multiply it by 1.000000e-18, to get kilofarads.
