Calorie (Th)/hour
Calorie per hour (cal(th)/h) is a unit of power representing the amount of heat energy in calories transferred or used per hour.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of 1 gram of water by 1°C, has been used in various contexts including nutrition and physics. The 'th' denotes the thermochemical calorie, an older standard. The unit cal(th)/h has been used historically in thermodynamics and heat transfer measurements.
Current Use
Today, cal(th)/h is rarely used in modern scientific contexts, having been largely replaced by SI units like watts. However, it may still appear in legacy systems or specialized fields involving heat transfer calculations.
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.
