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. 2,000 Cal is 8,368 kJ, so a tracker that says 2,000 Cal and a label that says 8,368 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 1,000 Cal, which is 4,184 kJ. Twice it is 4,000 Cal, which is 16,736 kJ.
