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. 3,000 Cal is 12,552 kJ, so a tracker that says 3,000 Cal and a label that says 12,552 kJ describe the same energy.
This is a large amount of energy. It is usually a total across many foods rather than a single item.
For scale, half of this amount is 1,500 Cal, which is 6,276 kJ. Twice it is 6,000 Cal, which is 25,104 kJ.
