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 (Th)
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 unit to quantify heat energy, especially in nutrition and thermodynamics. It was widely adopted in the early 20th century for dietary energy measurement.
Current Use
Today, the kilocalorie is primarily used in nutrition to express the energy content of food and drinks, although it is often simply called a 'calorie' in everyday language.
