2. Multiply the kilocalories (kcal) by 4.185 to find the number of kilojoules (kJ). Note that 1 kcal = 4.184 kJ. So, to convert from kilocalories to kilojoules, multiply by 4.185. [6] For example, multiply 0.025 kcal by 4.184 to get 0.105 kJ. So, 25 calories is equal to 0.105 kilojoules. Burning 1,000 calories a day is easier for some people than others. For example, a 6-foot, 3-inch 18-year-old male playing on multiple sports teams might easily burn more than 1,000 calories a day The Protein Calculator estimates the daily amount of dietary protein adults require to remain healthy. Children, those who are highly physically active, and pregnant and nursing women typically require more protein. The calculator is also useful for monitoring protein intake for those with kidney disease, liver disease, diabetes, or other The energy requirements calculator estimates your daily energy requirements for good health based on what your body needs for breathing, circulating blood, digesting food and physical activity. This may change from day to day. Any energy intake above the estimated requirement is likely to result in weight gain. How to convert Kilojoules to Calories (kJ to cal)? 1 kJ = 239.00573613767 cal. 1 x 239.00573613767 cal = 239.00573613767 Calories. Always check the results; rounding errors may occur. Definition: In relation to the base unit of [energy] => (joules), 1 Kilojoules (kJ) is equal to 1000 joules, while 1 Calories (cal) = 4.184 joules. Since one kilojoule is equal to 1,000 joules, you can use this simple formula to convert: joules = kilojoules × 1,000. The energy in joules is equal to the energy in kilojoules multiplied by 1,000. For example, here's how to convert 5 kilojoules to joules using the formula above. joules = (5 kJ × 1,000) = 5,000 J. AI-generated answer. To determine the number of calories in a candy bar containing 919,600 J of energy, we need to convert the given energy from joules to calories.1 calorie is equal to 4.184 joules.So, the number of calories can be calculated as follows:919,600 J x (1 cal / 4.184 J) = 219,979.65 calTherefore, there are approximately 219,979.65 1000 calories = 1 Calorie (dietary) 1,000 joules = 1 kilojoule (kJ) 1 calorie = 4.184 joules → 1 Calorie = 4.184 kJs. How does One Calorie Equal One Kilojoule? Even though we just showed that 1 Calorie is 4.184 kJs, the body is not 100% efficient at using that Calorie. Q249TR.
