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. 50 Cal is 209.2 kJ, so a tracker that says 50 Cal and a label that says 209.2 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 25 Cal, which is 104.6 kJ. Twice it is 100 Cal, which is 418.4 kJ.
