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.
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.
