How the formula works
Both gigawatt and megawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in gigawatts by 1000 to get megawatts. To reverse the conversion, multiply a megawatt value by 0.001 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 Megawatt (MW)?
A Megawatt (MW) equals 1e+6 watt(s), a scaled unit of electrical power used for mega-scale electrical work.
How do I convert gigawatts to megawatts?
Multiply the gigawatt value by 1000 to get the equivalent in megawatts. For example, 5 GW × 1000 = 5000 MW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert megawatts back to gigawatts?
Yes. Divide the megawatt value by 1000, or multiply it by 0.001, to get gigawatts.
