Picojoule/second
A picojoule per second (pJ/s) is a unit of power equivalent to one trillionth of a joule per second, representing an extremely small rate of energy transfer.
History/Origin
The picojoule per second is derived from the SI units of energy (joule) and time (second), with 'pico' denoting a factor of 10^-12. It has been used in scientific contexts requiring precise measurement of very small power levels, especially in fields like nanotechnology and low-power electronics.
Current Use
This unit is used in scientific and engineering applications to quantify extremely low power levels, such as in nanotechnology, bioelectronics, and other fields where minute energy transfer rates are relevant.
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.
