How the formula works
Both gigawatt and picowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigawatts by 1.000000e+21 to get picowatts. To reverse the conversion, multiply a picowatt value by 1.000000e-21 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 Picowatt (pW)?
A Picowatt (pW) equals 1e-12 watt(s), a scaled unit of electrical power used for pico-scale electrical work.
How do I convert gigawatts to picowatts?
Multiply the gigawatt value by 1.000000e+21 to get the equivalent in picowatts. For example, 5 GW × 1.000000e+21 = 5.000000e+21 pW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+21 is an exact, non-rounded value.
Can I convert picowatts back to gigawatts?
Yes. Divide the picowatt value by 1.000000e+21, or multiply it by 1.000000e-21, to get gigawatts.
