Conversion Formula
The formula for converting joules (j) to calories (cal) is:
cal = j × 0.239005736
The calorie used here is the small calorie (cal), which is the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius. Joule is the SI unit of energy. By multiplying joules with the factor 0.239005736, the energy in joules is converted to the equivalent number of calories.
For example, to convert 477 j to cal:
- Multiply 477 by 0.239005736
- 477 × 0.239005736 = 114.0563 cal
Conversion Example
- Convert 350 j to cal:
- Multiply 350 by 0.239005736
- 350 × 0.239005736 = 83.6519 cal
- So, 350 j equals approximately 83.6519 cal
- Convert 500 j to cal:
- 500 × 0.239005736 = 119.5029 cal
- Therefore, 500 j equals about 119.5029 cal
- Convert 600 j to cal:
- 600 × 0.239005736 = 143.4034 cal
- Thus, 600 j is equal to 143.4034 cal
- Convert 420 j to cal:
- 420 × 0.239005736 = 100.3824 cal
- Hence, 420 j converts to 100.3824 cal
- Convert 480 j to cal:
- 480 × 0.239005736 = 114.7228 cal
- So, 480 j is about 114.7228 cal

Conversion Definitions
j (joule): The joule is the SI unit of energy, defined as the work done when a force of one newton moves an object one meter in the direction of the force. It measures energy, work, or heat, used in physics and engineering fields globally.
cal (calorie): The calorie is a unit of energy, often used to quantify heat or food energy. One calorie is the amount of energy required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.
Conversion FAQs
Why is the conversion factor from joules to calories not a whole number?
The conversion factor 0.239005736 is derived from the physical properties of water and energy units. Because joules and calories are defined differently, based on mechanical energy and heat energy respectively, the factor represents the precise ratio between them, resulting in a decimal.
Can I use this conversion for dietary calories?
No, the calorie used here (small calorie) differs from the dietary Calorie (large Calorie or kilocalorie). One dietary Calorie equals 1000 small calories, so conversion between joules and dietary Calories requires a different factor.
Do the rounding errors affect energy calculations significantly?
Rounding to four decimal places introduces minimal error, usually negligible in practical uses. For highly precise scientific work, more decimals or exact constants may be necessary, but for everyday conversions, this precision is adequate.
Is it possible to convert calories back to joules?
Yes, by dividing the calorie value by the conversion factor or multiplying by its inverse (about 4.184), you can convert calories back to joules. This process reverses the conversion formula exactly.
Does temperature affect the joule to calorie conversion?
The basic conversion factor assumes standard conditions; however, tiny variations might occur if water’s heat capacity changes with temperature. Generally, these differences are too small to affect the conversion for most applications.
