Calorie (Th)/hour
Calorie per hour (cal(th)/h) is a unit of power representing the amount of heat energy in calories transferred or used per hour.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of 1 gram of water by 1°C, has been used in various contexts including nutrition and physics. The 'th' denotes the thermochemical calorie, an older standard. The unit cal(th)/h has been used historically in thermodynamics and heat transfer measurements.
Current Use
Today, cal(th)/h is rarely used in modern scientific contexts, having been largely replaced by SI units like watts. However, it may still appear in legacy systems or specialized fields involving heat transfer calculations.
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.
