Femtojoule/second
A femtojoule per second (fJ/s) is a unit of power representing the rate of energy transfer of one femtojoule (10^-15 joules) per second.
History/Origin
The femtojoule/second unit emerged with the development of high-precision measurements in nanotechnology and quantum physics, where extremely small energy transfer rates are relevant. It is derived from the SI units of energy (joule) and time (second), with 'femto' denoting 10^-15.
Current Use
The femtojoule/second is used in scientific research to quantify very small power levels, particularly in fields like nanotechnology, quantum computing, and molecular physics, where energy transfer rates are extremely low.
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.
