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 It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.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.
Watt-Hour
A watt-hour (W·h) is a unit of energy equal to the amount of energy transferred or used when one watt of power is sustained for one hour.
History/Origin
The watt-hour was established as a practical unit of energy measurement with the adoption of the International System of Units (SI) and has been used in electrical and energy industries to quantify energy consumption and storage since the 20th century.
Current Use
Watt-hours are commonly used to measure electrical energy consumption in household appliances, batteries, and energy storage systems, providing a convenient unit for billing, capacity ratings, and energy management.
