This chart converts kilojoules (kJ) to Calories (kcal) for every value you’re likely to meet on a food label, menu or fitness tracker. Each Calorie figure is calculated as kJ ÷ 4.184 and rounded to one decimal place. For a single number, use the kJ to calories converter, for everything at a glance, bookmark or print this page.
Quick rule: kcal = kJ ÷ 4.184 (or kJ × 0.239). 1,000 kJ = 239 kcal. 8,700 kJ = 2,079 kcal.

Every Single kJ Value
This chart shows common steps. For any exact number, 575, 1,160, 2,733 kJ and so on, use the searchable range tables, which list every value:
- 1 to 499 kJ
- 500 to 999 kJ
- 1,000 to 1,499 kJ
- 1,500 to 1,999 kJ
- 2,000 to 2,499 kJ

- 3,000 to 4,999 kJ
- 5,000 to 12,000 kJ
How To Read This Chart
- Kilojoules: the value you’re converting from.
- Calories (kcal): the equivalent in food Calories. Remember 1 Calorie = 1 kcal.
- Walking / Running: approximate time for a 70 kg adult to use that much energy walking at about 5 km/h (MET 3.5) or running at 8 km/h (MET 8.3). Heavier people take less time; lighter people take more.
- % of 8,700 kJ day: the share of the average adult daily intake used on Australian and New Zealand food labels.
How The Numbers Are Calculated
Every figure uses the internationally agreed conversion 1 kcal = 4.184 kJ:
- Calories = kilojoules ÷ 4.184
- Walking minutes = Calories ÷ (3.5 × 3.5 × 70 ÷ 200)
- Running minutes = Calories ÷ (8.3 × 3.5 × 70 ÷ 200)
- % daily intake = kilojoules ÷ 8,700 × 100
Values are rounded for display. If you need more decimal places, the converter on the home page shows two.
Handy Benchmarks To Remember
| Kilojoules | Calories | What it looks like |
|---|---|---|
| 100 kJ | 24 kcal | A teaspoon of sugar plus a splash of milk |
| 400 kJ | 96 kcal | A medium apple or small banana |
| 600 kJ | 143 kcal | A regular flat white with full-cream milk |
| 1,000 kJ | 239 kcal | A 45 g bag of potato chips |
| 2,000 kJ | 478 kcal | A sandwich and a small juice |
| 3,000 kJ | 717 kcal | A cheeseburger with medium fries and a small soft drink |
| 8,700 kJ | 2,079 kcal | Average adult day (AU/NZ labels) |

KJ To Calories Chart FAQ
What is the formula used in this chart?
Calories (kcal) = kilojoules ÷ 4.184. It’s the standard factor used on food labels and in nutrition science.
Can I print this chart?
Yes. Use your browser’s print option, the site header, footer and buttons are hidden automatically so only the content prints.
Why do the exercise times differ from my fitness tracker?
The chart uses average MET values for a 70 kg adult. Trackers estimate from your own heart rate, weight and movement, so their numbers vary.
Is 1,000 kJ a lot?
1,000 kJ is 239 Calories, about 11% of an average 8,700 kJ day. It’s a typical amount for a substantial snack or a small meal.
