      Relation Between Gigawatt (GW) and Watt (W)

      Let me explain to you about the relation between Gigawatt GW and Watt (W) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Gigawatt (GW)?

      A gigawatt (GW) is a unit of power equal to one billion watts (10⁹ watts). Gigawatt (GW) is a unit of power measurement which is commonly used in Engine power. Used in describing large-scale energy production, such as power plants or national power grids. Equivalent to 1,000 megawatts. Highlights the capacity of large electrical generators or renewable energy sources..

      What is Watt (W)?

      Gigawatt (GW) is another unit of power measurement that is used in . A watt (W) is the SI unit of power, defined as one joule per second.. Used in describing large-scale energy production, such as power plants or national power grids. Equivalent to 1,000 megawatts. Highlights the capacity of large electrical generators or renewable energy sources..

      How to Convert Watt (W)?

      The conversion between Gigawatt (GW) and Watt (W) follows a simple formula:

      Gigawatt = Gigawatt × 1000000000

      Where, 1000000000 is the value that allows you to convert between Gigawatt (GW) and Watt (W).

      So,

      1 Watt = 1000000000 Gigawatt

      And, 1 Gigawatt = 1/1000000000 Watt
