Gigawatts to Megawatts converter

To convert gigawatts to megawatts, enter the value in the first field. The result in megawatts is calculated automatically using the exact conversion factor.

1 GW = 1000 MW
1 MW = 0.001 GW

Formula: MW = GW × 1000
GW = MW × 0.001

Definitions: 1 GW = 1000000000 W; 1 MW = 1000000 W

The gigawatt (GW) is one billion watts. It is used for the capacity of large power plants and national grids, and a large nuclear reactor produces roughly one gigawatt of electricity.

The megawatt (MW) is one million watts. It is used for power plants, wind turbines, data centers and industrial facilities.
