1,350 kJ On A Food Label
If 1,350 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 |
|---|---|---|---|
| 40 g serve | 3,375 kJ | 807 kcal | high |
| 60 g serve | 2,250 kJ | 538 kcal | high |
| 100 g serve | 1,350 kJ | 323 kcal | medium |
| 150 g serve | 900 kJ | 215 kcal | medium |
| 250 g serve | 540 kJ | 129 kcal | low |
For example, if a 60 g serve contains 1,350 kJ, the food has about 2,250 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.
