How to Convert Megawatt to Watt

To convert from Megawatt (MW) to Watt (W), multiply the value by 1,000,000.

Formula: W = MW × 1,000,000

Reverse: MW = W × 0.000001

Step-by-Step Example

Start with your value in Megawatt. For example: 5 MW
Multiply by the conversion factor: 5 x 1,000,000
The result is: 5,000,000 W

About Megawatt

The megawatt (MW) is a unit of power. One megawatt equals 1.000000 × 10^+6 watts. UnitConvertLab converts it against every other power unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: power calculations, engineering and science, education.

About Watt

The watt (W) is a unit of power. One watt equals 1 watt. UnitConvertLab converts it against every other power unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
