This converter allows you to convert gigawatts [GW] to terawatts [TW] or terawatts [TW] to gigawatts [GW]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 gigawatt [GW] = 0.001 terawatts [TW]1 terawatt [TW] = 1,000 gigawatts [GW]

Convert gigawatts to terawatts

There are two simple ways to convert gigawatts [GW] to terawatts [TW]. In the first calculation method, the value in gigawatts [GW] is divided by 1,000. The second method multiplies the value in gigawatts [GW] by 0.001.

  • Terawatts [TW] = gigawatts [GW] ÷ 1,000
  • Terawatts [TW] = gigawatts [GW] * 0.001

Convert terawatts to gigawatts
