Calorie (Th)/second
Calorie (th)/second (cal(th)/s) is a unit of power representing the rate at which thermal calories are transferred or converted per second.
History/Origin
The calorie (th), or thermochemical calorie, was historically used to quantify energy in thermodynamics and nutrition. Its use in power measurement, such as cal(th)/s, emerged in scientific contexts to express thermal energy transfer rates before the adoption of the watt as the standard SI unit.
Current Use
Today, cal(th)/s is rarely used in scientific practice, having been largely replaced by watts (W). It may still appear in specialized fields or historical references related to thermal energy transfer rates.
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.
