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.
Joule/hour
A joule per hour (J/h) is a unit of power representing the amount of energy (in joules) transferred or converted per hour.
History/Origin
The joule per hour has been used as a measure of power in various scientific and engineering contexts, especially where energy transfer rates are expressed over longer periods. It is derived from the SI unit of energy, the joule, divided by time in hours.
Current Use
Joule per hour is occasionally used in fields like heating, energy consumption, and industrial processes to quantify power over extended durations, though it is less common than watts for standard power measurements.
