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 It may still appear in specialized fields or historical references related to thermal energy transfer rates.
Btu (It)/second
Btu per second (Btu/s) is a unit of power representing the rate of energy transfer or conversion, where one British thermal unit (Btu) is transferred or converted every second.
History/Origin
The Btu (British thermal unit) has been used historically to measure energy, especially in heating and cooling industries. The use of Btu per second as a power unit emerged to quantify energy transfer rates in engineering and scientific contexts, aligning with the broader adoption of the Btu in energy measurement.
Current Use
Btu/s is used primarily in engineering and energy industries to specify power levels, such as in heating, cooling, and energy transfer systems, although it is less common than SI units like watts.
