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 It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts.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.
Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
