Power is energy per unit of time; the SI unit, the watt, is one joule per second. Cars are rated in horsepower or kilowatts, air conditioners in BTU per hour or tons of refrigeration, and power plants in megawatts or gigawatts. Note that "horsepower" has two common meanings: the mechanical (imperial) horsepower of 745.7 W used in the US and UK, and the metric horsepower (PS, CV) of 735.5 W used in Europe and Brazil.
