250 kilojoules (kJ) is equal to approximately 59.7585 calories (cal).
This conversion is done by multiplying the energy value in kilojoules by the factor 0.239006, which converts the unit from kJ to calories. This is because 1 kilojoule equals about 0.239006 calories, allowing energy measurements to be expressed in different units.

Conversion Formula
The formula to convert kilojoules to calories is:
calories = kilojoules × 0.239006
This formula works because 1 kilojoule equals approximately 0.239006 calories. Kilojoule and calorie both measure energy but on different scales, so multiply the kilojoule value by this factor to get calories.
For example, converting 250 kJ to calories:
- Start with 250 kJ.
- Multiply 250 by 0.239006.
- 250 × 0.239006 = 59.7515 calories.
- Rounded to four decimals, 59.7585 calories.
Conversion Example
- 100 kJ to calories
- Multiply 100 by 0.239006.
- 100 × 0.239006 = 23.9006 calories.
- Result: about 23.9006 calories.
- 175 kJ to calories
- 175 × 0.239006 = 41.8259 calories.
- So, 175 kJ equals 41.8259 calories.
- 300 kJ to calories
- 300 × 0.239006 = 71.7018 calories.
- This means 300 kJ is 71.7018 calories.
- 425 kJ to calories
- 425 × 0.239006 = 101.678 calories.
- Therefore, 425 kJ converts to 101.678 calories.

Conversion Definitions
kj: Kilojoule (kJ) is a unit of energy used in the metric system, representing 1,000 joules. It measures energy, work, or heat, and often used in nutrition to indicate the energy content of foods. It’s part of the International System of Units (SI).
calories: The calorie (cal) is a unit of energy most commonly used to express the amount of energy food provides. One calorie is the energy needed to raise 1 gram of water by 1 °C. In nutrition, the term calorie usually means kilocalorie (1,000 calories).
Conversion FAQs
Why does multiplying by 0.239006 convert kJ to calories?
This number is the exact ratio between kilojoules and calories. One kilojoule equals 0.239006 calories because calories are a smaller unit of energy, so multiplying by this factor converts the larger unit kJ into the smaller calorie unit.
Can I convert calories back to kilojoules using the same formula?
No, to convert calories back to kilojoules, you must divide calories by 0.239006 or multiply by approximately 4.184 since 1 calorie equals 4.184 joules. The conversion factor is reversed.
What’s the difference between a calorie and a Calorie with capital ‘C’?
A capitalized Calorie (Cal) is actually a kilocalorie, equal to 1,000 calories (cal). Nutrition labels usually use Calorie to indicate kilocalories. So 250 kJ corresponds to about 59.7585 small calories, or about 0.05975 Calories.
Are kilojoules and calories interchangeable in food labels?
While they both express energy, food labels use either kJ or Calories depending on region. You can convert between them, but they are not interchangeable in writing. The numeric value changes due to unit size.
Will the conversion factor change over time or by country?
No, the conversion factor is internationally standardized based on physics constants. It won’t change by country or over time, so 1 kJ always equals 0.239006 calories.
