The working

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. 400 kJ is 95.6 Cal, so a label that says 400 kJ and a tracker that says 95.6 Cal describe the same energy.

This is a small amount of energy, closer to a single piece of fruit or a drink than to a meal.

For scale, half of this amount is 200 kJ, which is 47.8 Cal. Twice it is 800 kJ, which is 191.2 Cal.
