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.
Foot Pound-Force/hour
Foot pound-force per hour (ft*lbf/h) is a unit of power representing the amount of work done in foot-pounds over the period of one hour.
History/Origin
The foot pound-force is an imperial unit of work or energy, and its use in power measurements like ft*lbf/h has been common in engineering fields in the United States. It has been used historically in mechanical and thermodynamic contexts before the adoption of SI units.
Current Use
Today, ft*lbf/h is primarily used in specific engineering applications, such as in the measurement of small power outputs in mechanical systems, though it is largely replaced by SI units like watts in most scientific and international contexts.
