This converter allows you to convert gigawatts [GW] to nanowatts [nW] or nanowatts [nW] 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.
Convert gigawatts to nanowatts
There are two simple ways to convert gigawatts [GW] to nanowatts [nW]. In the first calculation method, the value in gigawatts [GW] is divided by 10-18. The second method multiplies the value in gigawatts [GW] by 1018.
- Nanowatts [nW] = gigawatts [GW] ÷ 10-18
- Nanowatts [nW] = gigawatts [GW] * 1018
Convert nanowatts to gigawatts
