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.


Kilocalorie (It)/hour

Kilocalorie per hour (kcal/h) is a unit of power representing the rate at which energy in kilocalories is transferred or converted per hour.

History/Origin

The kilocalorie, often used in nutrition and energy measurement, has been adopted as a unit of energy. Its use in power measurement, such as kcal/h, emerged in contexts like thermal and caloric power calculations, especially in fields related to heating and energy transfer.

Current Use

kcal/h is used in applications involving thermal power, such as heating systems, calorimetry, and energy transfer calculations where energy flow is expressed in kilocalories per hour.
