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 (Th)/hour
Btu (th)/hour is a unit of power that measures the rate of energy transfer, specifically the amount of thermal energy in British thermal units (Btu) delivered or consumed per hour.
History/Origin
The Btu (th)/hour originated from the British thermal unit (Btu), a traditional unit of heat energy, and has been used primarily in the heating and energy industries to quantify thermal power rates. Its usage dates back to the early 20th century as a standard measure in thermal energy calculations.
Current Use
Today, Btu (th)/hour is used mainly in the heating, ventilation, and air conditioning (HVAC) industry, as well as in energy consumption and efficiency assessments, to specify thermal power rates of equipment and systems.
