How the formula works
Both petawatt and gigawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petawatts by 1.000000e+06 to get gigawatts. To reverse the conversion, multiply a gigawatt value by 0.000001 to get back to petawatts.
Frequently asked questions
What is Petawatt (PW)?
A Petawatt (PW) equals 1e+15 watt(s), a scaled unit of electrical power used for peta-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 petawatts to gigawatts?
Multiply the petawatt value by 1.000000e+06 to get the equivalent in gigawatts. For example, 5 PW × 1.000000e+06 = 5.000000e+06 GW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+06 is an exact, non-rounded value.
Can I convert gigawatts back to petawatts?
Yes. Divide the gigawatt value by 1.000000e+06, or multiply it by 0.000001, to get petawatts.
