Kilojoules and calories
One calorie (kcal) is 4.184 kilojoules. So 8,700 kJ, the reference figure on many Australian labels, works out to about 2,080 calories.
Australia and New Zealand print energy in kilojoules first and the US prints calories, which is why the same snack can show two very different numbers. Quick conversions, label reading and setting a daily target in either unit are all covered here.
