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 It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.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
A therm 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 by the American Gas Association to standardize natural gas billing and measurement; it became widely adopted in North America for energy calculations.
Current Use
Today, the therm is still used in the natural gas industry for billing and energy measurement, although other units like gigajoules and cubic meters are also common globally.
