Convert horsepower (water) to watts
Horsepower (water)
Water horsepower (hp) is a unit of power used in the context of pumps and hydraulic systems, defined as the minimum power required to move a given volume of water against a given pressure. It is equal to approximately 746 watts, very close to mechanical horsepower, and is calculated from flow rate and head pressure. This unit is primarily used by pump engineers in the United States to express hydraulic power output. It should not be confused with mechanical or metric 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.
