How the formula works
Both megawatt and exawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megawatts by 1.000000e-12 to get exawatts. To reverse the conversion, multiply a exawatt value by 1.000000e+12 to get back to megawatts.
Frequently asked questions
What is Megawatt (MW)?
A Megawatt (MW) equals 1e+6 watt(s), a scaled unit of electrical power used for mega-scale electrical work.
What is Exawatt (EW)?
An Exawatt (EW) equals 1e+18 watt(s), a scaled unit of electrical power used for exa-scale electrical work.
How do I convert megawatts to exawatts?
Multiply the megawatt value by 1.000000e-12 to get the equivalent in exawatts. For example, 5 MW × 1.000000e-12 = 5.000000e-12 EW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-12 is an exact, non-rounded value.
Can I convert exawatts back to megawatts?
Yes. Divide the exawatt value by 1.000000e-12, or multiply it by 1.000000e+12, to get megawatts.
