Calorie (Nutritional)
A calorie (Cal) is a unit of energy used to measure the amount of energy provided by food and beverages, specifically representing the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie was first introduced in the 19th century as a unit to quantify energy in nutrition. It has since become a standard measure in dietary and nutritional contexts, although the scientific community often prefers the joule as the SI unit of energy.
Current Use
Calories are widely used in nutrition to quantify the energy content of food and beverages, helping consumers manage dietary intake and energy balance. The term 'Calorie' with a capital 'C' typically refers to kilocalories (kcal), which are equivalent to 1,000 small calories.
Microjoule
A microjoule (µJ) is a unit of energy equal to one millionth of a joule, used to measure small amounts of energy.
History/Origin
The microjoule was introduced as part of the metric system to facilitate the measurement of very small energy quantities, especially in scientific and engineering contexts, with the adoption of the International System of Units (SI).
Current Use
Microjoules are commonly used in fields such as electronics, physics, and biology to quantify small energy transfers, signals, or reactions, often in research and technical applications.
