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. 50 kJ is 11.95 Cal, so a label that says 50 kJ and a tracker that says 11.95 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 25 kJ, which is 5.98 Cal. Twice it is 100 kJ, which is 23.9 Cal.
