What is Horsepower (mechanical)?

Horsepower is a unit of power devised by James Watt to compare steam engine performance to the work of draft horses. One mechanical horsepower equals approximately 745.7 watts. Car engine output is commonly described in horsepower, with typical passenger cars producing 100 to 200 hp and sports cars 300 to 600 hp. In the United States, horsepower remains the standard measure for engine power, vehicle performance, and industrial motor ratings.

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.
