How the formula works
Both farad and attofarad measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in farads by 1.000000e+18 to get attofarads. To reverse the conversion, multiply a attofarad value by 1.000000e-18 to get back to farads.
Frequently asked questions
What is Farad (F)?
The farad (F) is the SI unit of capacitance, measuring a capacitor's ability to store electric charge per volt.
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 farads to attofarads?
Multiply the farad value by 1.000000e+18 to get the equivalent in attofarads. For example, 5 F × 1.000000e+18 = 5.000000e+18 aF.
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 attofarads back to farads?
Yes. Divide the attofarad value by 1.000000e+18, or multiply it by 1.000000e-18, to get farads.
