Attojoule/second
An attojoule per second (aJ/s) is a unit of power representing the rate of energy transfer or conversion of one attojoule (10^-18 joules) per second.
History/Origin
The attojoule is a relatively recent SI prefix introduced to measure extremely small quantities of energy, and its use in power units like aJ/s has emerged with advancements in nanotechnology and quantum physics, though it remains a specialized unit with limited historical usage.
Current Use
The aJ/s is used in scientific research involving extremely low power measurements, such as in quantum physics, nanotechnology, and energy transfer studies at the atomic or molecular scale.
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.
