Calorie (Th)
The calorie (th) is a unit of energy used to quantify the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie (th) was historically used in the context of thermochemistry and nutrition, originating from the calorie concept in the 19th century. It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.
Current Use
Today, the calorie (th) is primarily used in nutrition labeling and food energy measurements, especially in regions where the thermochemical calorie is still recognized, although the joule is the SI standard.
Therm (Us)
The therm (US) is a unit of energy used primarily to measure natural gas consumption, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm was introduced in the early 20th century as a practical unit for billing natural gas, standardizing energy measurement in the United States. It has been widely adopted in the energy industry for commercial and residential gas usage.
Current Use
Today, the therm (US) is still used in the natural gas industry for billing and energy calculations, although it has been largely supplemented by the gigajoule and other SI units in scientific contexts.
