This converter allows you to convert watts [W] to gigawatts [GW] or gigawatts [GW] to watts [W]. 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 watt [W] = 10-9 gigawatts [GW]1 gigawatt [GW] = 109 watts [W]

Convert watts to gigawatts

There are two simple ways to convert watts [W] to gigawatts [GW]. In the first calculation method, the value in watts [W] is divided by 109. The second method multiplies the value in watts [W] by 10-9.

  • Gigawatts [GW] = watts [W] ÷ 109
  • Gigawatts [GW] = watts [W] * 10-9

Convert gigawatts to watts

Converting gigawatts [GW] to watts [W] is easy and can be done in two ways. The first method involves multiplication, whereby the value in gigawatts [GW] is multiplied by 109. The second variant is a division. Here, the value in gigawatts [GW] is divided by 10-9.

  • Watts [W] = gigawatts [GW] * 109
  • Watts [W] = gigawatts [GW] ÷ 10-9
