How the formula works
Both femtovolt and quectovolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtovolts by 1.000000e+15 to get quectovolts. To reverse the conversion, multiply a quectovolt 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 Quectovolt (qV)?
A Quectovolt (qV) equals 1e-30 volt(s), a scaled unit of electric potential used for quecto-scale electrical work.
How do I convert femtovolts to quectovolts?
Multiply the femtovolt value by 1.000000e+15 to get the equivalent in quectovolts. For example, 5 fV × 1.000000e+15 = 5.000000e+15 qV.
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 quectovolts back to femtovolts?
Yes. Divide the quectovolt value by 1.000000e+15, or multiply it by 1.000000e-15, to get femtovolts.
