Calorie (It)/hour
Calorie per hour (cal/h) is a unit of power that measures the rate at which energy in calories is transferred or consumed over time.
History/Origin
The calorie has been used historically in nutrition and thermodynamics to quantify energy. The cal/h unit emerged in contexts where energy transfer rates were expressed in calories per hour, particularly in heating and metabolic studies.
Current Use
Cal/h is used in specific scientific and engineering applications, such as measuring heat transfer rates, metabolic rates, and in some thermal engineering contexts, although it is less common than SI units like watts.
Microjoule/second
The microjoule per second (µJ/s) is a unit of power representing the rate of energy transfer or conversion, where one microjoule equals 10^-6 joules, transferred per second.
History/Origin
The microjoule per second originated from the need to measure very small power levels in scientific and engineering contexts, especially in fields like electronics and nanotechnology, as a scaled-down unit of the watt (joule per second).
Current Use
It is used in applications requiring precise measurement of low power levels, such as in microelectromechanical systems (MEMS), sensor technology, and research involving minute energy transfers.
