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.
Btu (It)/hour
Btu (IT)/hour (Btu/h) is a unit of power that measures the rate of energy transfer, specifically the amount of British thermal units (IT) transferred per hour.
History/Origin
The Btu (IT) originated from the British thermal unit used in the United States and was standardized for industrial and engineering purposes. The per-hour notation became common in applications requiring power measurement, especially in heating and cooling systems.
Current Use
Btu/h is widely used in heating, ventilation, and air conditioning (HVAC) industries to specify the capacity of heating and cooling equipment, as well as in energy analysis and thermodynamics.
