Therm (Ec)
The therm (EC) is a unit of energy used primarily in the measurement of natural gas and heating energy, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm originated in the early 19th century as a practical unit for measuring large quantities of heat energy, especially in the gas industry, and has been standardized in various regions for energy billing and calculations.
Current Use
Today, the therm (EC) is used mainly in the natural gas industry and energy sectors to quantify heat energy consumption, although it has largely been supplemented or replaced by SI units like joules and kilowatt-hours in many regions.
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 It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts.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.
