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.
Microwatt
A microwatt (µW) is a unit of power equal to one millionth of a watt, used to measure very small amounts of power.
History/Origin
The microwatt was introduced as part of the metric system's effort to provide standardized units for small quantities of power, especially in scientific and technological contexts, gaining prominence with the adoption of the International System of Units (SI).
Current Use
Microwatts are used in fields such as electronics, telecommunications, and biomedical engineering to quantify low power levels in devices, sensors, and circuits.
