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.
Calories (cal)
Definition
A calorie (cal), also known as a small calorie or gram calorie, is defined as the amount of heat energy needed to raise the temperature of one gram of water by one degree Celsius. It equals approximately 4.184 joules.
History
The calorie was first defined by French chemist Nicolas Clément in 1824. It was widely used in chemistry and physiology before the joule became the official SI unit of energy.
Current use
Small calories are used in chemistry and physics for heat measurements. In everyday language, 'calorie' often refers to the kilocalorie (kcal) when discussing food energy.
