Convert horsepower (electric) to watts
Horsepower (Electric)
The electric horsepower (hp) is a unit of power defined as exactly 746 watts, standardized for use in rating the output of electric motors in the United States. It differs slightly from the mechanical (imperial) horsepower of approximately 745.7 watts and the metric horsepower of 735.499 watts. The electric horsepower is the legal definition used by the U.S. Federal Trade Commission for labeling motor-driven products.
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.
