How the formula works
Both attovolt and femtovolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attovolts by 0.001 to get femtovolts. To reverse the conversion, multiply a femtovolt value by 1000 to get back to attovolts.
Frequently asked questions
What is Attovolt (aV)?
An Attovolt (aV) equals 1e-18 volt(s), a scaled unit of electric potential used for atto-scale electrical work.
What is Femtovolt (fV)?
A Femtovolt (fV) equals 1e-15 volt(s), a scaled unit of electric potential used for femto-scale electrical work.
How do I convert attovolts to femtovolts?
Multiply the attovolt value by 0.001 to get the equivalent in femtovolts. For example, 5 aV × 0.001 = 0.005 fV.
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 femtovolts back to attovolts?
Yes. Divide the femtovolt value by 0.001, or multiply it by 1000, to get attovolts.
