How the formula works
Both watt and megawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in watts by 0.000001 to get megawatts. To reverse the conversion, multiply a megawatt value by 1.000000e+06 to get back to watts.
Frequently asked questions
What is Watt (W)?
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
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 watts to megawatts?
Multiply the watt value by 0.000001 to get the equivalent in megawatts. For example, 5 W × 0.000001 = 0.000005 MW.
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 megawatts back to watts?
Yes. Divide the megawatt value by 0.000001, or multiply it by 1.000000e+06, to get watts.
