1,500 kJ On A Food Label
If 1,500 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 |
|---|---|---|---|
| 60 g serve | 2,500 kJ | 598 kcal | high |
| 100 g serve | 1,500 kJ | 359 kcal | medium |
| 150 g serve | 1,000 kJ | 239 kcal | medium |
| 250 g serve | 600 kJ | 143 kcal | medium |
Take a 60 g serve: 1,500 kJ ÷ 60 × 100 = 2,500 kJ per 100 g, which puts it in the high-density group alongside biscuits, chips, chocolate, nuts and oils. The food label calculator does this for any label.
