What Does 100 Horsepower Mean?

[DiBeau]

100 horsepower is defined as follows: 1. Definition: 100 horsepower is equivalent to the work done to lift a 75-kilogram object 100 meters per second. 2. Origin: Horsepower was proposed by James Watt and is a commonly used unit of power measurement in engineering. It generally refers to metric horsepower rather than imperial horsepower. By convention, 1 metric horsepower is defined as the work done to lift a 75-kilogram object 1 meter per second. 3. Imperial Horsepower: Countries such as the UK and the US use imperial horsepower. 1 imperial horsepower equals 550 foot-pounds per second, or 745.7 watts. In the late 18th century, British physicist James Watt defined horsepower as the work required to lift a 1,000-pound weight 33 feet in one minute to measure the power of newly manufactured steam engines. This is known as imperial horsepower, denoted by the letter HP.
