This converter turns megawatts into watts instantly, using the exact factor 1 megawatt = 1000000 watts. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
The unit for power stations and grid-scale generation. The SI unit of power: one joule per second.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
megawatts- The amount you are converting, measured in megawatts
1000000- The exact number of watts in one megawatt
watts- The converted result
How it works, step by step
- Enter the number of megawatts you want to convert.
- The value is multiplied by 1000000, the exact conversion factor.
- The result is displayed in watts, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 megawatts
Multiply 5 by 1000000. That gives 5,000,000 watts. A quick sanity check: one megawatt is larger than one watt, so the number should get bigger — and it does.
Converting 72 megawatts
72 × 1000000 = 72,000,000 watts. Working backwards, 72,000,000 ÷ 1000000 returns 72 megawatts, which confirms the factor is applied the right way round.

Frequently asked questions
How many watts are in one megawatt?
Exactly 1000000. Every conversion on this page is that single number multiplied by your input, so the result carries no rounding error beyond what is shown.
What is the formula to convert megawatts to watts?
Watts = megawatts × 1000000. To reverse it, divide instead: megawatts = watts ÷ 1000000, which is the same as multiplying by 1e-06.
Is the megawatt bigger than the watt?
Yes. One megawatt equals 1e+06 watts, so it is the larger unit.
Why does my answer differ slightly from other megawatts to watts converters?
Most differences come from rounding the factor too early. This tool keeps full double precision through the calculation and only rounds at the final display step, and it also shows the unrounded value so you can see exactly where any difference appears.
