Btu (It)
The Btu (IT) is a unit of energy used to measure the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit, based on the International Table (IT) standards.
History/Origin
The Btu (IT) originated from the British thermal unit, adapted for international standards to provide a consistent measurement of heat energy, particularly in engineering and thermodynamics contexts.
Current Use
The Btu (IT) is primarily used in the energy industry, including heating, cooling, and power generation, to quantify energy content and efficiency in systems adhering to international standards.
Calorie (It)
The calorie (cal) is a unit of energy traditionally used to quantify the amount of heat required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.
History/Origin
The calorie was originally defined in the 19th century as a unit of heat energy in thermodynamics. It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts. The 'small calorie' (cal) is distinct from the 'large calorie' (kcal), which is commonly used in food energy labeling.
Current Use
Today, the calorie is primarily used in nutrition to measure the energy content of foods and beverages, although the SI unit of energy, the joule, is increasingly preferred in scientific and technical fields.
