      Relation Between Megawatt (MW) and Gigawatt (GW)

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

      What is Megawatt (MW)?

      A megawatt (MW) is a unit of power equal to one million watts (10⁶ watts). Megawatt (MW) is a unit of power measurement which is commonly used in Air conditioning. Common in describing medium- to large-scale energy systems, such as wind farms or hydroelectric dams. Equivalent to 1,000 kilowatts. Highlights substantial energy production and consumption capacities..

      What is Gigawatt (GW)?

      Megawatt (MW) is another unit of power measurement that is used in Engine power. A gigawatt (GW) is a unit of power equal to one billion watts (10⁹ watts).. Common in describing medium- to large-scale energy systems, such as wind farms or hydroelectric dams. Equivalent to 1,000 kilowatts. Highlights substantial energy production and consumption capacities..

      How to Convert Gigawatt (GW)?

      The conversion between Megawatt (MW) and Gigawatt (GW) follows a simple formula:

      Megawatt = Megawatt × 0.001

      Where, 0.001 is the value that allows you to convert between Megawatt (MW) and Gigawatt (GW).

      So,

      1 Gigawatt = 0.001 Megawatt

      And, 1 Megawatt = 1/0.001 Gigawatt
