Kilocalorie (It)/minute
A unit of power representing the energy expended or transferred at a rate of one kilocalorie per minute.
History/Origin
The kilocalorie (kcal) has historically been used to measure energy in food and nutrition, while the minute as a time unit has been standard in timekeeping. Combining these, kcal/min was used to quantify power, especially in contexts like metabolic rates and energy expenditure, before the widespread adoption of the watt as the SI unit of power.
Current Use
The kcal/min is primarily used in fields such as physiology and sports science to express rates of energy expenditure, though it is less common today with the adoption of the watt (W) as the standard SI unit of power.
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.
