Kilojoules (kJ)
Definition
A kilojoule (kJ) is a unit of energy equal to 1,000 joules. It is commonly used for expressing larger quantities of energy in nutritional contexts and engineering.
History
The kilojoule naturally derives from the joule with the SI kilo- prefix. It gained widespread use in the 20th century, particularly in countries adopting the metric system for food energy labeling.
Current use
Kilojoules are the primary energy unit on food labels in Australia, New Zealand, and many European countries. They are also used in heating, ventilation, and chemical energy calculations.
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.
