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)/hour
A kilocalorie (th)/hour (kcal(th)/h) is a unit of power representing the rate at which energy in kilocalories per hour is transferred or converted.
History/Origin
The kilocalorie, often used in nutrition and energy measurement, has been adapted into various units including the thermochemical kilocalorie (kcal(th)). Its use in power measurement, such as kcal(th)/h, is primarily for specialized scientific and engineering applications, integrating energy units with time to express power.
Current Use
The kcal(th)/h unit is used in contexts requiring the measurement of energy transfer rates in thermochemical terms, such as in thermal engineering, calorimetry, and energy efficiency assessments where energy flow is expressed in kilocalories per hour.
