To convert megawatts to watts, multiply by 1000000.
The calculation uses 1 MW = 1000000 W. Results are displayed to at most 10 significant digits. Definitions can be exact while a displayed decimal is rounded. Match the displayed precision to your original measurement.
The formula
value in W = value in MW × 1000000
MW- Input unit: megawatts
W- Output unit: watts
How to use this calculator
- Enter a value in MW.
- Multiply by the stored conversion factor.
- Read the result in W; divide by the same factor to convert back.
Worked examples
Worked conversion
1 MW × 1000000 ≈ 1000000 W.
Reverse conversion
1000000 W ÷ 1000000 ≈ 1 MW. Rounding intermediate values can change the last displayed digit.
Frequently asked questions
What factor does this converter use?
It uses 1000000 W per MW.
Why can another converter show a slightly different answer?
Check the unit convention first (such as US versus Imperial or decimal versus binary), then compare rounding. Measurement uncertainty is separate from the unit conversion.
