kJ, Calories and kcal

Kilojoules (kJ) are the metric unit of energy, and food labels in Australia, New Zealand, the UK and the EU give energy in them. A food Calorie, written Cal here and also called kcal, is the other common unit. 8,400 kJ is 2,007.65 Cal, so a label that says 8,400 kJ and a tracker that says 2,007.65 Cal describe the same energy.

This is a large amount of energy. It is usually a total across many foods rather than a single item.

For scale, half of this amount is 4,200 kJ, which is 1,003.82 Cal. Twice it is 16,800 kJ, which is 4,015.3 Cal.
