Megajoules (MJ)
Definition
A megajoule (MJ) is a unit of energy equal to 1,000,000 joules (10⁶ J). It is used to express large-scale energy quantities.
History
The megajoule became commonly used with the growth of industrial energy measurement in the 20th century, particularly for fuel energy content and large engineering systems.
Current use
Megajoules are used to express the energy content of fuels (e.g., natural gas, gasoline), industrial process energy, and large-scale thermal systems in engineering and environmental science.
Kilocalories (kcal)
Definition
A kilocalorie (kcal), also known as a food calorie or large calorie, equals 1,000 small calories or approximately 4,184 joules. It is the standard unit for measuring dietary energy.
History
The kilocalorie became the standard unit for food energy labeling in the United States and many other countries during the 20th century. Nutritionist Wilbur Olin Atwater pioneered its use in dietary science.
Current use
Kilocalories are the primary unit for food energy on nutrition labels in the US, Canada, and much of Asia. They are also used in exercise science, dietetics, and metabolic rate calculations.
