The watt (symbol: W) is a derived unit of power in the International System of Units (SI) defined as 1 joule per second and can be used to quantify the rate of energy transfer. Power has dimensions of ML2T-3.
| 1 watts = 1.0E-9 gigawatts | 6 watts = 6.0E-9 gigawatts |
| 2 watts = 2.0E-9 gigawatts | 7 watts = 7.0E-9 gigawatts |
| 3 watts = 3.0E-9 gigawatts | 8 watts = 8.0E-9 gigawatts |
| 4 watts = 4.0E-9 gigawatts | 9 watts = 9.0E-9 gigawatts |
| 5 watts = 5.0E-9 gigawatts | 10 watts = 1.0E-8 gigawatts |
The gigawatt (GW) is equal to one billion (109) watts or 1 gigawatt = 1000 megawatts. This unit is often used for large power plants or power grids. For example, by the end of 2010 power shortages in China's Shanxi province were expected to increase to 5–6 GW and the installed capacity of wind power in Germany was 25.8 GW. The largest unit (out of four) of the Belgian Doel Nuclear Power Station has a peak output of 1.04 GW. HVDC converters have been built with power ratings of up to 2 GW.

| 2 gigawatts = 2000000000 watts | 7 gigawatts = 7000000000 watts |
| 3 gigawatts = 3000000000 watts | 8 gigawatts = 8000000000 watts |
| 4 gigawatts = 4000000000 watts | 9 gigawatts = 9000000000 watts |
| 5 gigawatts = 5000000000 watts | 10 gigawatts = 10000000000 watts |
