650 kJ On A Food Label
If 650 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 |
|---|---|---|---|
| 25 g serve | 2,600 kJ | 621 kcal | high |
| 40 g serve | 1,625 kJ | 388 kcal | high |
| 60 g serve | 1,083 kJ | 259 kcal | medium |
| 100 g serve | 650 kJ | 155 kcal | medium |
| 150 g serve | 433 kJ | 104 kcal | low |
| 250 g serve | 260 kJ | 62 kcal | low |
For example, if a 60 g serve contains 650 kJ, the food has about 1,083 kJ per 100 g, a medium-density food, similar to bread, lean meat, eggs and pasta dishes. The food label calculator does this for any label.
