Calorie (It)/second
Calorie per second (cal/s) is a unit of power representing the rate at which energy in calories is transferred or converted per second.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius, has been used in various contexts including nutrition and thermodynamics. The use of calories per second as a power unit became common in scientific and engineering fields to quantify energy transfer rates before the adoption of the SI unit watt.
Current Use
Calorie per second is primarily used in scientific research, thermodynamics, and certain engineering applications to measure power, especially in contexts where energy transfer in calories is relevant. It is less common in everyday use, having been largely replaced by the watt (W) in SI units.
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.
