2,400 kJ On A Food Label
If 2,400 kJ is the per-serve figure on a nutrition panel, check the serving size next to it. Here is how the energy per 100 g changes with the size of that serve.
| Serving size | kJ per 100 g | kcal per 100 g | Energy density |
|---|---|---|---|
| 100 g serve | 2,400 kJ | 574 kcal | high |
| 150 g serve | 1,600 kJ | 382 kcal | high |
| 250 g serve | 960 kJ | 229 kcal | medium |
For example, if a 100 g serve contains 2,400 kJ, the food has about 2,400 kJ per 100 g, a high-density food, similar to biscuits, chips, chocolate, nuts and oils. The food label calculator does this for any label.
