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.
Hectojoule/second
Hectojoule per second (hJ/s) is a unit of power representing one hundred joules of energy transferred or converted per second.
History/Origin
The unit hJ/s is derived from the SI unit joule (J) and the metric prefix hecto- (h), used to express larger quantities of energy transfer rate, particularly in scientific and engineering contexts. It has been used as an alternative to watts in certain fields, though watts are more standard.
Current Use
Hectojoule per second is occasionally used in scientific and engineering applications to quantify power, especially in contexts where larger energy transfer rates are involved. However, the watt (W) remains the standard SI unit for power, and hJ/s is less common in everyday use.
