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. 80 Cal is 334.72 kJ, so a tracker that says 80 Cal and a label that says 334.72 kJ 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 40 Cal, which is 167.36 kJ. Twice it is 160 Cal, which is 669.44 kJ.
