Horsepower (550 Ft*lbf/s)
Horsepower (hp) is a unit of power measurement, defined as 550 foot-pounds of work per second (ft·lbf/s).
History/Origin
The horsepower was developed by James Watt in the late 18th century to compare the power of steam engines with draft horses, and it became a standard unit for measuring engine power.
Current Use
Horsepower is still widely used today to rate the power of engines and motors in automotive, aviation, and industrial applications.
Pound-Foot/second
A pound-foot per second (lbf·ft/s) is a unit of power representing the rate at which work is done or energy is transferred, equivalent to one pound-force acting through a distance of one foot per second.
History/Origin
The pound-foot per second has been used primarily in engineering contexts within the Imperial system to quantify power, especially in mechanical and automotive applications, though it is less common than other units like horsepower.
Current Use
Today, the pound-foot per second is rarely used; it is mainly referenced in historical data or specific engineering calculations involving Imperial units, with the more standard unit of power being the horsepower or the watt in SI units.
