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.
Kilocalorie (Th)/second
A kilocalorie (th)/second (kcal(th)/s) is a unit of power representing the rate at which energy in kilocalories per second is transferred or converted.
History/Origin
The kilocalorie (th) is a traditional unit of energy used primarily in nutrition and thermodynamics, with 'th' indicating the thermochemical definition. Its use in power measurements, such as kcal(th)/s, is less common and primarily for specialized scientific contexts.
Current Use
The unit kcal(th)/s is rarely used in modern practice; power is more commonly expressed in watts. When used, it typically appears in scientific research involving energy transfer rates in thermochemical processes or specialized engineering applications.
