How to Convert Megawatt to Milliwatt

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

Formula: mW = MW × 1.000000e+9

Reverse: MW = mW × 1.000000e-9

Step-by-Step Example

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

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 Milliwatt

The milliwatt (mW) is a unit of power. One milliwatt equals 0.001 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.
