The energy in kilojoules is equal to the energy in calories multiplied by 0.004184. For example, here's how to convert 500 calories to kilojoules using the formula above. kilojoules = (500 cal × 0.004184) = 2.092 kJ. Calories and kilojoules are both units used to measure energy. Keep reading to learn more about each unit of measure. kilojoule (kJ) joule (J) calories and kilocalories. kilocalorie (kcal) calorie (cal) watt x time. kilowatt hour (kWh) megawatt hour (MWh) watt hour (Wh) watt second (Ws) energy equivalent units. kg of oil equivalent (koe) tonne of oil equivalent (toe) thousand tonnes of oil equivalent (ktoe) million tonnes of oil equivalent (Mtoe) barrel of oil 29 kJ: 6.93 Calorie (nutritional) 30 kJ: 7.17 Calorie (nutritional) 31 kJ: 7.41 Calorie (nutritional) 32 kJ: 7.65 Calorie (nutritional) 33 kJ: 7.89 Calorie (nutritional) 34 kJ: 8.13 Calorie (nutritional) 35 kJ: 8.37 Calorie (nutritional) 36 kJ: 8.60 Calorie (nutritional) 37 kJ: 8.84 Calorie (nutritional) 38 kJ: 9.08 Calorie (nutritional) 39 kJ The more you weigh, the more you burn during a session. Walking at a speed of 3.5 miles per hour, you burn between 240 and 356 calories per hour, advises Harvard Health Publishing. This is the same calorie burn as an hour of water aerobics. If you increase your speed to 4 miles per hour, you burn between 270 and 400 calories per hour. 30 Calories to Joules = 125.52. 1,000 Calories to Joules = 4184. 40 Calories to Joules = 167.36. 10,000 Calories to Joules = 41840. 50 Calories to Joules = 209.2. 100,000 Calories to Joules = 418400. 60 Calories to Joules = 251.04. 1,000,000 Calories to Joules = 4184000. The unit of energy is the kilojoule (kJ) or megajoule (1 MJ = 1,000 kJ) 4.18 kilojoules are equal to 1 kilocalorie. Allowing for intestinal absorption and for the nitrogenous parts of protein that cannot be completely oxidised, the average amount of energy released ranges from approximately 16.7 kJ/g for carbohydrates or protein to 29.3 kJ/g For instance, a typical 160-pound person of average height will burn about 40 calories per 1,000 steps. This is the equivalent of 0.04 calories per step. The charts below show you how many calories you'd burn in 1,000 steps, 5,000 steps, 10,000 steps, or more. Here is what you need to know about converting your steps to calories burned. How to Convert Kilograms to Calories. By. Joe Sexton. To convert a measurement in kilograms to a measurement in calories, multiply the weight by the following conversion ratio: 7,716.179176 calories/kilogram. Since one kilogram of body fat is equal to 7,716.179176 calories, you can use this simple formula to convert: calories = kilograms × FMET.
