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.
Kilojoule/hour
A kilojoule per hour (kJ/h) is a unit of power representing the amount of energy in kilojoules transferred or converted per hour.
History/Origin
The kilojoule per hour has been used as a measure of power in contexts where energy transfer rates are expressed over time, particularly in engineering and scientific applications, though it is less common than standard SI units like watts.
Current Use
kJ/h is used in specific fields such as thermodynamics and energy management to quantify energy transfer rates, especially in systems where energy is measured in kilojoules and the rate is expressed per hour, though it is often converted to watts for standardization.
