How the formula works
Both gigawatt and petawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigawatts by 0.000001 to get petawatts. To reverse the conversion, multiply a petawatt value by 1.000000e+06 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 Petawatt (PW)?
A Petawatt (PW) equals 1e+15 watt(s), a scaled unit of electrical power used for peta-scale electrical work.
How do I convert gigawatts to petawatts?
Multiply the gigawatt value by 0.000001 to get the equivalent in petawatts. For example, 5 GW × 0.000001 = 0.000005 PW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.000001 is an exact, non-rounded value.
Can I convert petawatts back to gigawatts?
Yes. Divide the petawatt value by 0.000001, or multiply it by 1.000000e+06, to get gigawatts.
