Conversion Formula
The formula to convert kilojoules (kJ) to calories (cal) involves multiplying the number of kilojoules by 0.239005736. This factor comes from the energy equivalence: 1 kilojoule equals approximately 0.239 calories.
This works because a calorie is a smaller unit of energy than a kilojoule; therefore, when converting, you multiply by a number less than one to get the calorie amount.
Example calculation for 1400 kJ:
- Multiply 1400 by 0.239005736
- 1400 × 0.239005736 = 334.40799
- Rounded to two decimals, 334.41 calories
Conversion Example
- Convert 1000 kJ to calories:
– Multiply 1000 × 0.239005736 = 239.0057 calories.
– So, 1000 kJ is approximately 239.01 calories. - Convert 500 kJ to calories:
– Multiply 500 × 0.239005736 = 119.5029 calories.
– Result: about 119.50 calories. - Convert 2500 kJ to calories:
– Multiply 2500 × 0.239005736 = 597.5143 calories.
– Equals roughly 597.51 calories. - Convert 750 kJ to calories:
– Multiply 750 × 0.239005736 = 179.2543 calories.
– About 179.25 calories.

Conversion Definitions
kj: Kilojoule (kJ) is a unit of energy in the metric system, equal to 1,000 joules. It measure energy transfer or work done, often used in food energy content and physics. Kilojoules quantify the energy amount stored in food or released in processes.
calories: The calorie is a unit of energy originally based on heating water. It measures the amount of energy food provides when metabolized. In nutrition, the calorie usually means kilocalorie (Cal), which is 1,000 true calories, representing energy used by the body.
Conversion FAQs
Why do we multiply kilojoules by 0.239 to get calories?
Because one kilojoule equals approximately 0.239 calories. The calorie is smaller than a kilojoule, so to convert from kJ to cal, you multiply by this factor to get the equivalent energy in calories.
Can I use this conversion for all types of calories?
There are “small” calories and “large” calories (kilocalories). The conversion factor applies to the small calories. In food energy, calories usually mean kilocalories, so you must be sure which calorie unit is used before converting.
Is converting 1400 kj to calories precise?
The conversion is accurate within standard rounding limits. The factor 0.239005736 is precise, but slight differences can happen due to rounding. For everyday use, the result is reliable enough for diet and energy calculations.
Does the conversion change based on food type?
No, the conversion is a fixed physical constant between units of energy. Food type doesn’t affect the numerical conversion from kilojoules to calories, but nutritional values depend on the food’s composition.
How to convert calories back to kilojoules?
To convert calories to kilojoules, divide the calories value by 0.239005736 or multiply by 4.184. This reverses the conversion, as 1 calorie equal 4.184 kilojoules.
