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.
Nanojoule/second
A nanojoule per second (nJ/s) is a unit of power representing the transfer or conversion of one nanojoule of energy per second.
History/Origin
The nanojoule per second is derived from the SI units of energy (joule) and time (second), with 'nano' indicating a factor of 10^-9. It is used in contexts requiring very small power measurements, especially in scientific and engineering fields.
Current Use
The nJ/s is used in scientific research, nanotechnology, and precise energy transfer measurements where extremely low power levels are involved, often in the context of nanoscale systems or experiments.
