Btu (Th)
The Btu (th), or British thermal unit (th), is a unit of energy used primarily in the United States to measure heat content, equivalent to the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit.
History/Origin
The Btu (th) originated from the British thermal unit, a traditional unit of heat in the British Imperial system, and has been used historically in heating, cooling, and energy industries to quantify energy content and heat transfer.
Current Use
Today, the Btu (th) is mainly used in the energy sector, particularly in heating and cooling systems, natural gas billing, and energy content measurement, especially within the United States.
Kilocalorie (It)
A kilocalorie (kcal) is a unit of energy equal to 1,000 calories, commonly used to measure the energy content of food and beverages.
History/Origin
The kilocalorie originated in the 19th century as a measure of heat energy, primarily used in nutrition and thermodynamics. It became standard in dietary contexts to quantify food energy intake.
Current Use
Today, the kilocalorie is widely used in nutrition to express the energy content of foods and beverages, and in scientific contexts related to energy measurement in biological and physical systems.
