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. 1,800 kJ is 430.21 Cal, so a label that says 1,800 kJ and a tracker that says 430.21 Cal describe the same energy.

This is the size of a single meal or a large serve of one dish.

For scale, half of this amount is 900 kJ, which is 215.11 Cal. Twice it is 3,600 kJ, which is 860.42 Cal.
