Conversion Formula
The formula to convert joules (j) to calories (cal) is:
calories = joules × 0.239005736
This works because one calorie is defined as approximately 4.184 joules, so to convert joules to calories, you divide the number of joules by 4.184. Multiplying by the reciprocal, 0.239005736, gives the calories value directly.
For example, for 24 joules:
- Divide 24 by 4.184: 24 ÷ 4.184 = 5.7337 calories
- Or multiply 24 by 0.239005736: 24 × 0.239005736 = 5.7337 calories
Conversion Example
- Convert 10 j to calories:
- Multiply 10 by 0.239005736
- 10 × 0.239005736 = 2.3901 calories
- So, 10 j = 2.3901 calories
- Convert 50 j to calories:
- 50 × 0.239005736 = 11.9503 calories
- So, 50 j = 11.9503 calories
- Convert 5 j to calories:
- 5 × 0.239005736 = 1.1950 calories
- Therefore, 5 j equals 1.1950 calories
- Convert 100 j to calories:
- 100 × 0.239005736 = 23.9006 calories
- Hence, 100 j equals 23.9006 calories

Conversion Definitions
j: The joule (symbol: j) is the SI unit of energy, work, or heat. It quantifies energy transferred when one newton force moves an object one meter. It is commonly used in physics and engineering to measure mechanical, electrical, or thermal energy quantities.
calories: The calorie, abbreviated as cal, is a unit of energy widely used to quantify heat or food energy. One calorie is the amount of heat energy required to raise the temperature of one gram of water by one degree Celsius, used in nutrition and thermodynamics.
Conversion FAQs
Can negative joules be converted to calories?
Yes, negative joules can be converted to calories. Negative values indicate energy loss or removal, and multiplying by the conversion factor keeps the sign, representing negative calories. Although less common, it’s valid for certain physical contexts.
Why does the conversion factor between joules and calories have so many decimal places?
The conversion factor 0.239005736 is precise to provide accurate results across applications. Since joule and calorie are defined differently, the decimal places ensure minimal rounding errors, especially important in scientific calculations requiring precision.
Is the calorie used here the dietary calorie?
No. The calorie in this conversion is the “small calorie” or gram calorie, which is different from the dietary Calorie (kilocalorie). One dietary Calorie equals 1000 small calories. So, 24 j converts to about 5.7 small calories, which is 0.0057 dietary Calories.
Can I convert joules to calories without a calculator?
It’s possible to estimate by remembering 1 j ≈ 0.24 cal, but for exact conversion, using a calculator or tool is better because the factor has many decimal places and the result might be off if rounded too much.
What happens if I convert joules to calories with very large values?
The formula works for all values, big or small. For large numbers, the calorie figure will also be large. Computer or calculator precision might affect the last digits, but the formula remains valid for all practical energy conversions.
