How to Convert Watt to Gigawatt

1 watt = 1 × 10-9 gigawatts

Gigawatt = Watt × 1 × 10-9

Example: 2.5 × 108 W × 1 × 10-9 = 14 GW

Reverse Conversion

To convert gigawatts back to watts:

  • Remember, 1 gigawatt equals 1 × 109 watts.
  • To convert 14 GW to W, multiply 14 x 1 × 109, resulting in 2.5 × 108 W.

2.5 × 108 W is also equal to:

  • 250000 kilowatt
  • 250 megawatt
  • 335120 horsepower (electric)
