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.


Btu (Th)/second

Btu (th)/second is a unit of power representing the rate of energy transfer, specifically one British thermal unit (th) per second.

History/Origin

The British thermal unit (th) has been used historically in the United States for measuring heat energy, and its use in power units like Btu (th)/s dates back to traditional energy and heat transfer calculations in engineering and thermodynamics.

Current Use

Btu (th)/second is primarily used in the United States for industrial and engineering applications involving heat transfer rates, although it is less common compared to SI units like watts.
