How the formula works
Both femtovolt and volt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtovolts by 1.000000e-15 to get volts. To reverse the conversion, multiply a volt value by 1.000000e+15 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 Volt (V)?
The volt (V) is the SI unit of electric potential difference, the "push" that drives current through a circuit.
How do I convert femtovolts to volts?
Multiply the femtovolt value by 1.000000e-15 to get the equivalent in volts. For example, 5 fV × 1.000000e-15 = 5.000000e-15 V.
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 volts back to femtovolts?
Yes. Divide the volt value by 1.000000e-15, or multiply it by 1.000000e+15, to get femtovolts.
