About Units

Joules per second: Joules per second (J/s) is a unit of power equivalent to watts in the International System of Units (SI). One joule per second is the rate at which one joule of energy is transferred or converted in one second. It is commonly used in scientific contexts to measure energy transfer rates.

Gigawatt: The gigawatt (GW) is a unit of power equal to one billion watts. Gigawatts are used to measure the capacity of very large power plants and the total power consumption of entire countries. For example, the total electrical generating capacity of a large nuclear power plant can be around 1 gigawatt.
