How the formula works
Both megawatt and watt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megawatts by 1.000000e+06 to get watts. To reverse the conversion, multiply a watt value by 0.000001 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 Watt (W)?
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
How do I convert megawatts to watts?
Multiply the megawatt value by 1.000000e+06 to get the equivalent in watts. For example, 5 MW × 1.000000e+06 = 5.000000e+06 W.
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 watts back to megawatts?
Yes. Divide the watt value by 1.000000e+06, or multiply it by 0.000001, to get megawatts.
