Double burger with special sauce (1 burger), 2,301 kJ
About 6 × apple, medium (397 kJ each)
About 5.5 × banana, medium (439 kJ each)
About 8 × egg, large (301 kJ each)
About 7.5 × white bread, 1 slice (335 kJ each)
About 4 × flat white, full-cream milk (628 kJ each)
About 3.5 × cola, regular (674 kJ each)

Values are typical, the food kJ chart lists 120+ foods.

2,440 kJ On A Food Label

A label line that reads “2,440 kJ per serve” only tells half the story. Divide by the serve size and you get the energy density, how much energy is packed into every 100 g of the food.

Serving size	kJ per 100 g	kcal per 100 g	Energy density
100 g serve	2,440 kJ	583 kcal	high
150 g serve	1,627 kJ	389 kcal	high
250 g serve	976 kJ	233 kcal	medium

kJ per 100 g = 2,440 ÷ serve weight × 100. Rows above 3,700 kJ per 100 g (pure fat) are not possible and are not shown.

For example, if a 100 g serve contains 2,440 kJ, the food has about 2,440 kJ per 100 g, a high-density food, similar to biscuits, chips, chocolate, nuts and oils. Scale any pack to your portion with the food label calculator.
