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. 25 Cal is 104.6 kJ, so a tracker that says 25 Cal and a label that says 104.6 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 12.5 Cal, which is 52.3 kJ. Twice it is 50 Cal, which is 209.2 kJ.
