What is Metric horsepower?

Metric horsepower (PS) is defined as the power to lift 75 kilograms by one meter in one second, equal to approximately 735.5 watts. The abbreviation comes from the German "Pferdestärke" (horse strength). It is the standard unit for automotive power in Japan, Germany, and much of continental Europe. Japanese car specifications typically list maximum output in PS. One PS is slightly less than one mechanical horsepower (hp).

What is Watt?

The watt is the SI unit of power, named after Scottish inventor James Watt. One watt equals one joule of energy per second. Household LED bulbs use about 7 to 12 watts, a microwave oven uses 500 to 1,000 watts, and a hair dryer uses about 1,200 watts. Electricity bills are based on watt-hours, the product of power consumption in watts and time of use.
