How the formula works
Both gigawatt and femtowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigawatts by 1.000000e+24 to get femtowatts. To reverse the conversion, multiply a femtowatt value by 1.000000e-24 to get back to gigawatts.
Frequently asked questions
What is Gigawatt (GW)?
A Gigawatt (GW) equals 1e+9 watt(s), a scaled unit of electrical power used for giga-scale electrical work.
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 gigawatts to femtowatts?
Multiply the gigawatt value by 1.000000e+24 to get the equivalent in femtowatts. For example, 5 GW × 1.000000e+24 = 5.000000e+24 fW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+24 is an exact, non-rounded value.
Can I convert femtowatts back to gigawatts?
Yes. Divide the femtowatt value by 1.000000e+24, or multiply it by 1.000000e-24, to get gigawatts.
