Convert mechanical horsepower to watts
Mechanical Horsepower
Mechanical horsepower (hp), defined as 550 foot-pounds-force per second, is equal to exactly 745.69987 watts. It was introduced by James Watt to compare the output of steam engines to that of draft horses, and became the standard horsepower in the United States and United Kingdom for mechanical and automotive applications. It is distinct from metric horsepower (PS) and boiler horsepower.
Watt
The watt (symbol: W ) is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 joule per second, and is used to quantify the rate of energy transfer. In SI base units, the watt is described as kg⋅m 2 ⋅s −3 , which can be demonstrated to be coherent by dimensional analysis. The watt is named after James Watt, an 18th-century Scottish inventor.
