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 It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.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.
Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
