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.
Btu (Th)/second
Btu (th)/second is a unit of power representing the rate of energy transfer, specifically one British thermal unit (th) per second.
History/Origin
The British thermal unit (th) has been used historically in the United States for measuring heat energy, and its use in power units like Btu (th)/s dates back to traditional energy and heat transfer calculations in engineering and thermodynamics.
Current Use
Btu (th)/second is primarily used in the United States for industrial and engineering applications involving heat transfer rates, although it is less common compared to SI units like watts.
