How the formula works
Both volt and femtowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in volts by 1.000000e+15 to get femtowatts. To reverse the conversion, multiply a femtowatt value by 1.000000e-15 to get back to volts.
Frequently asked questions
What is Volt (V)?
The volt (V) is the SI unit of electric potential difference, the "push" that drives current through a circuit.
What is Femtowatt (fW)?
A Femtowatt (fW) equals 1e-15 watt(s), a scaled unit of electrical power used for femto-scale electrical work.
How do I convert volts to femtowatts?
Multiply the volt value by 1.000000e+15 to get the equivalent in femtowatts. For example, 5 V × 1.000000e+15 = 5.000000e+15 fW.
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 femtowatts back to volts?
Yes. Divide the femtowatt value by 1.000000e+15, or multiply it by 1.000000e-15, to get volts.
