About Units

Horsepower: Horsepower (HP) is a unit of measurement of power, originally defined as 550 foot-pounds per second. It is commonly used to measure the power output of engines. For example, the engine of a car might be rated at 300 horsepower. There are different standards for horsepower, including mechanical horsepower, metric horsepower, and electrical horsepower.

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.
