How the formula works
Both femtovolt and attovolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtovolts by 1000 to get attovolts. To reverse the conversion, multiply a attovolt value by 0.001 to get back to femtovolts.
Frequently asked questions
What is Femtovolt (fV)?
A Femtovolt (fV) equals 1e-15 volt(s), a scaled unit of electric potential used for femto-scale electrical work.
What is Attovolt (aV)?
An Attovolt (aV) equals 1e-18 volt(s), a scaled unit of electric potential used for atto-scale electrical work.
How do I convert femtovolts to attovolts?
Multiply the femtovolt value by 1000 to get the equivalent in attovolts. For example, 5 fV × 1000 = 5000 aV.
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 attovolts back to femtovolts?
Yes. Divide the attovolt value by 1000, or multiply it by 0.001, to get femtovolts.
