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. 900 kJ is 215.11 Cal, so a label that says 900 kJ and a tracker that says 215.11 Cal describe the same energy.
This is a modest amount of energy, the size of a snack or a small drink.
For scale, half of this amount is 450 kJ, which is 107.55 Cal. Twice it is 1,800 kJ, which is 430.21 Cal.
