2,140 kJ On A Food Label

A label line that reads “2,140 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
60 g serve	3,567 kJ	852 kcal	high
100 g serve	2,140 kJ	511 kcal	high
150 g serve	1,427 kJ	341 kcal	medium
250 g serve	856 kJ	205 kcal	medium

kJ per 100 g = 2,140 ÷ serve weight × 100. Rows above 3,700 kJ per 100 g (pure fat) are not possible and are not shown.

Take a 60 g serve: 2,140 kJ ÷ 60 × 100 = 3,567 kJ per 100 g, which puts it in the high-density group alongside biscuits, chips, chocolate, nuts and oils. Scale any pack to your portion with the food label calculator.
