How the formula works
Both picowatt and gigawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picowatts by 1.000000e-21 to get gigawatts. To reverse the conversion, multiply a gigawatt value by 1.000000e+21 to get back to picowatts.
Frequently asked questions
What is Picowatt (pW)?
A Picowatt (pW) equals 1e-12 watt(s), a scaled unit of electrical power used for pico-scale electrical work.
What is Gigawatt (GW)?
A Gigawatt (GW) equals 1e+9 watt(s), a scaled unit of electrical power used for giga-scale electrical work.
How do I convert picowatts to gigawatts?
Multiply the picowatt value by 1.000000e-21 to get the equivalent in gigawatts. For example, 5 pW × 1.000000e-21 = 5.000000e-21 GW.
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 gigawatts back to picowatts?
Yes. Divide the gigawatt value by 1.000000e-21, or multiply it by 1.000000e+21, to get picowatts.
