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. 4,200 kJ is 1,003.82 Cal, so a label that says 4,200 kJ and a tracker that says 1,003.82 Cal describe the same energy.
This is more than most single servings, so it is usually a total across several items.
For scale, half of this amount is 2,100 kJ, which is 501.91 Cal. Twice it is 8,400 kJ, which is 2,007.65 Cal.
