1,260 kJ On A Food Label
If 1,260 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 | 3,150 kJ | 753 kcal | high |
| 60 g serve | 2,100 kJ | 502 kcal | high |
| 100 g serve | 1,260 kJ | 301 kcal | medium |
| 150 g serve | 840 kJ | 201 kcal | medium |
| 250 g serve | 504 kJ | 120 kcal | low |
For example, if a 60 g serve contains 1,260 kJ, the food has about 2,100 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.
