A kilojoule is a unit of measure of energy, in the same way that kilometres measure distance. Food energy used to be measured in Calories (Cal) and some countries still use those units. The conversions are as follows: 1 joule = 0.24 calories. 1 calorie = 4.184 joule. Energy from Protein: 5 g x 4 kcal/g = 20 kcal = 20 Cal. Convert to kJ. 20 Cal x 4.184kJ/Cal = 83.68 kJ = 84 kJ. Step 3: Think about your result . For the snack food in this example, most of the energy is coming from fat first, then from carbohydrates and finally from protein when these three sources of energy are considered. Imagine you’ve consumed 7,000 calories in excess of your daily maintenance calories. To calculate how this might affect your weight, apply the formula: WI = P = C / 3500. WI = P = 7,000 / 3500. WI = P = 2. So, consuming 7,000 extra calories could lead to an estimated weight increase of 2 pounds. FAQs (Frequently Asked Questions) 1.
