About Joules and Calories
One joule equals approximately 0.239 calories. The joule is the SI unit of energy, while the calorie is a traditional unit still widely used in nutrition and chemistry. In physics, energy is always expressed in joules, but food energy is commonly measured in calories (or kilocalories). Converting joules to calories is essential for students studying thermodynamics, chemists calculating reaction energy, and anyone bridging scientific and nutritional energy measurements.
