This was the definition used at the time within the existing system of units. History/origin: The watt is named after James Watt, a Scottish inventor. It is defined as 1 joule per second and is used to quantify the rate of energy transfer. WattÄefinition: A watt (Symbol: W) is the SI (International System of Units) derived unit of power. The term was later expanded to include other types of output power such as the imperial and metric horsepower measurements commonly used today. ![]() It is believed that Watt built on this idea and introduced the term horsepower, largely in an effort to market his steam engine. As early as 1702, Thomas Savery referenced horses when describing the output of an engine. Watt was not the first person to compare the output of horses to that of engines. History/origin: The term horsepower was adopted in the late 18 th century by James Watt to compare the output of steam engines with the power of draft horses. In addition, when rating electric motors, one horsepower is equal to 746 watts. Boiler horsepower, albeit a less common measurement than either imperial or metric horsepower, is used for rating steam boilers, and is equivalent to 34.5 pounds of water evaporated per hour at 212 degrees Fahrenheit, or 9809.5 watts. lbf/s), while metric horsepower is approximately 735.5 watts (75 kgf. ![]() Mechanical horsepower, also known as imperial horsepower, is defined as approximately 745.7 watts (550 ft Definition: The unit horsepower (symbol: hp) is a unit of measurement of power (the rate at which work is done). ![]()
