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.
Nanowatt
A nanowatt (nW) is a unit of power equal to one billionth of a watt (10^-9 W).
History/Origin
The nanowatt is derived from the SI unit watt, with the prefix 'nano-' indicating a factor of 10^-9. It has been used in scientific and engineering contexts to measure very small power levels, especially in electronics and nanotechnology.
Current Use
Nanowatts are used in fields requiring precise measurement of tiny power quantities, such as in sensor technology, low-power electronics, and nanotechnology research.
