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.
Millijoule/second
A millijoule per second (mJ/s) is a unit of power equivalent to one millijoule of energy transferred or converted every second.
History/Origin
The unit derives from the joule, the SI unit of energy, and the second, the SI unit of time. It has been used in contexts requiring small power measurements, especially in scientific and engineering applications, with the millijoule being a submultiple of the joule.
Current Use
Millijoule per second is used to measure small power levels in scientific experiments, electronics, and other fields where precise, small-scale power measurement is necessary, often within the context of energy transfer or consumption rates.
