Convert Megawatts to Watts
1 megawatt is 1,000,000 W. One megawatt is exactly 1000000 watts.
One megawatt is 1000000 watts. To convert megawatts to watts, multiply by 1000000; to go the other way, divide by 1000000 or multiply by 1.0000 × 10^-6. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A million watts.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert megawatts to watts?
- 1.Take the measurement in megawatts.
- 2.Multiply by 1000000 — that is how many watts fit in one megawatt.
- 3.To go back the other way, divide by 1000000, or multiply by 1.0000 × 10^-6.
Worked example: 25 megawatts to watts
- Formula
- MW × 1000000 = W
- Arithmetic
- 25 × 1000000 = 25,000,000 W
- Answer
- 25 MW = 25,000,000 W
The factor is exact, so this figure is exact too — only the display is rounded.

What is a megawatt?
A million watts. Generating plant and grid capacity are quoted in it: one megawatt runs roughly 750 homes in the US at average draw.
What is a watt?
The SI unit: one joule every second. A watt is a rate, not an amount, which is the distinction between it and the watt-hour on your electricity bill.
How many watts are in a megawatt?
One megawatt is 1000000 watts, exactly. Going the other way, one watt is 1.0000 × 10^-6 megawatts. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
