kJ, Calories and kcal

Calories are the unit most recipes and fitness apps use. A food Calorie, written Cal here and also called kcal, is 4.184 kJ, and kilojoules (kJ) are what many food labels show. 300 Cal is 1,255.2 kJ, so a tracker that says 300 Cal and a label that says 1,255.2 kJ 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 150 Cal, which is 627.6 kJ. Twice it is 600 Cal, which is 2,510.4 kJ.
