kJ stands for Kilojoule, an engineering unit abbreviation.

A thousand joules, the energy unit on food labels in Australia, New Zealand and the EU (alongside kcal) and in chemistry and physics problems. Australian labels use a reference adult intake of 8,700 kJ a day.

Example: Each 250 mL can contains 470 kJ, about 112 Calories.

Usage notes

Many Australians count kilojoules rather than calories, and menu boards in several Australian states must display kJ. Divide kJ by 4.184 to get kcal. Chemistry reports reaction enthalpies in kJ/mol, such as about 890 kJ/mol released when methane burns.
