Conversion Formula
To convert kilojoules to calories, the formula is:
Calories = Kilojoules × 0.239005736
This works because 1 kilojoule equals approximately 0.239005736 calories. The calorie here is the small calorie (cal), not the dietary Calorie (kcal). By multiplying the energy in kJ by this factor, you get the equivalent energy in calories.
Example calculation for 250 kJ:
- Start with 250 kJ
- Multiply by 0.239005736
- 250 × 0.239005736 = 59.751434
- Rounded result: 59.755 calories

Conversion Definitions
kj: Kilojoule (kJ) is an SI unit of energy equal to 1,000 joules. It measures work or heat energy transferred, commonly used in physics, engineering, and nutrition to quantify energy content or expenditure. 1 kJ is larger than 1 calorie, making it useful for larger energy values.
calories: A calorie (cal) is a unit of energy defined as the amount needed to raise the temperature of 1 gram of water by 1°C at standard pressure. It is widely used in chemistry and food science, but differs from the dietary Calorie (kcal) used on food labels, which is 1,000 calories.
Conversion FAQs
Does 250 kJ equal 60 dietary Calories?
No, 250 kJ equals about 60 small calories (cal), not dietary Calories (kcal). To get dietary Calories, divide the small calories by 1000. So, 250 kJ = ~59.755 cal, which is 0.059755 kcal, much less than 60 dietary Calories.
Can I use 0.24 as conversion factor from kJ to calories?
Using 0.24 is a rough approximation for converting kJ to calories, but the exact factor is 0.239005736. For more accurate results, especially in scientific contexts, use the precise value instead of 0.24 to avoid small errors.
Why is the multiplication used in kJ to calorie conversion?
Because one kilojoule contains a fixed number of calories, conversion requires multiplying by that constant. This multiplication converts the energy amount from one unit scale to another, preserving the actual energy value in different units.
Are calories and kilojoules interchangeable in nutrition?
Calories and kilojoules both measure energy but are not interchangeable without conversion. Food labels may use one or the other depending on region. Knowing the conversion factor helps to compare energy content accurately across units.
What causes conversion errors between kJ and calories?
Errors come from rounding the conversion factor, confusing small calories with dietary Calories, or using approximate values. Always confirm which calorie unit is used and use precise factors to minimize mistakes.
