This converter allows you to convert gigawatts [GW] to milliwatts [mW] or milliwatts [mW] 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] = 1012 milliwatts [mW]1 milliwatt [mW] = 10-12 gigawatts [GW]

Convert gigawatts to milliwatts

There are two simple ways to convert gigawatts [GW] to milliwatts [mW]. In the first calculation method, the value in gigawatts [GW] is divided by 10-12. The second method multiplies the value in gigawatts [GW] by 1012.

  • Milliwatts [mW] = gigawatts [GW] ÷ 10-12
  • Milliwatts [mW] = gigawatts [GW] * 1012

Convert milliwatts to gigawatts

Converting milliwatts [mW] to gigawatts [GW] is easy and can be done in two ways. The first method involves multiplication, whereby the value in milliwatts [mW] is multiplied by 10-12. The second variant is a division. Here, the value in milliwatts [mW] is divided by 1012.

  • Gigawatts [GW] = milliwatts [mW] * 10-12
  • Gigawatts [GW] = milliwatts [mW] ÷ 1012
