Gigawatts to Watts

One gigawatt equals 1000000000 watts, so any figure in GW becomes watts by multiplying it by that factor. Enter the power in gigawatts, press Convert, and the result in watts appears right away.

How to convert gigawatts to watts

Gigawatts and watts are both units of power, and the gigawatt is simply the larger of the two: 1 GW = 1000000000 W. Going the other way, 1 W = 0.000000001 GW, which is the same as 1/1000000000 GW.

To change a value from gigawatts into watts, multiply it by 1000000000. No other step is needed, and the tool below does the arithmetic for you: type the gigawatt figure, press Convert, then use Copy to keep the result or Clear to start over.

GW to watts formula

The power in watts P(W) equals one billion times the power in gigawatts P(GW): P(W) = 1000000000 x P(GW).

For example, converting 3 GW gives P(W) = 1000000000 x 3 GW = 3000000000 W. Small values work the same way: 0.001 GW x 1000000000 = 1000000 W, and 0.000001 GW x 1000000000 = 1000 W.
