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.
Picojoule/second
A picojoule per second (pJ/s) is a unit of power equivalent to one trillionth of a joule per second, representing an extremely small rate of energy transfer.
History/Origin
The picojoule per second is derived from the SI units of energy (joule) and time (second), with 'pico' denoting a factor of 10^-12. It has been used in scientific contexts requiring precise measurement of very small power levels, especially in fields like nanotechnology and low-power electronics.
Current Use
This unit is used in scientific and engineering applications to quantify extremely low power levels, such as in nanotechnology, bioelectronics, and other fields where minute energy transfer rates are relevant.
