- Dark chocolate 70% (20 g), 502 kJ
- Olive oil, 1 tbsp (14 g), 498 kJ
- Cappuccino, full-cream milk (regular), 502 kJ
- White wine (150 ml glass), 506 kJ
- About 1.5 × egg, large (301 kJ each)

500 kJ On A Food Label
If 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 |
|---|---|---|---|
| 25 g serve | 2,000 kJ | 478 kcal | high |
| 40 g serve | 1,250 kJ | 299 kcal | medium |
| 60 g serve | 833 kJ | 199 kcal | medium |
| 100 g serve | 500 kJ | 120 kcal | low |
| 150 g serve | 333 kJ | 80 kcal | low |
| 250 g serve | 200 kJ | 48 kcal | very low |
For example, if a 60 g serve contains 500 kJ, the food has about 833 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.
