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 (Th)/hour

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

History/Origin

The kilocalorie, often used in nutrition and energy measurement, has been adapted into various units including the thermochemical kilocalorie (kcal(th)). Its use in power measurement, such as kcal(th)/h, is primarily for specialized scientific and engineering applications, integrating energy units with time to express power.

Current Use

The kcal(th)/h unit is used in contexts requiring the measurement of energy transfer rates in thermochemical terms, such as in thermal engineering, calorimetry, and energy efficiency assessments where energy flow is expressed in kilocalories per hour.
