Kilocalories and joules are both units of energy measurement. Kilocalorie is commonly used to measure energy in the food we consume, while joule is a unit used in physics to measure energy.

To convert kilocalories to joules, multiply the number of kilocalories by 4,184. For example, 1 kcal is equal to 4,184 J.

Similarly, to convert joules to kilocalories, divide the number of joules by 4,184. For example, 1,000 J is equal to 0.239 kcal.
