About Calorie (thermochemical) (cal)
The small calorie (cal) is the energy needed to raise one gram of water by one degree Celsius at standard pressure. While largely replaced by the joule in scientific contexts (1 cal = 4.184 J exactly), the calorie remains in use in chemistry and is the basis for the food Calorie (kilocalorie).
About Kilojoule (kJ)
Equal to 1,000 joules, the kilojoule is the standard energy unit on food nutrition labels in Australia, New Zealand, and the European Union. A typical adult's daily energy requirement is about 8,700 kJ (approximately 2,080 kilocalories), and food packages in metric countries display energy content in kJ.
