Kilojoule [kJ] 0.01 kcal (th) 0.04184 kJ: 0.1 kcal (th) 0.4184 kJ: 1 kcal (th) 4.184 kJ: 2 kcal (th) 8.368 kJ: 3 kcal (th) 12.552 kJ: 5 kcal (th) 20.92 kJ: 10 kcal (th) 41.84 kJ: 20 kcal (th) 83.68 kJ: 50 kcal (th) 209.2 kJ: 100 kcal (th) 418.4 kJ: 1000 kcal (th) 4184 kJ To convert a measurement in calories to a measurement in kilojoules, multiply the energy by the following conversion ratio: 0.004184 kilojoules/calorie. Since one calorie is equal to 0.004184 kilojoules, you can use this simple formula to convert: kilojoules = calories × 0.004184. Quick conversion chart of calories to kJ 1 calories to kJ = 0.00419 kJ 10 calories to kJ = 0.04186 kJ 50 calories to kJ = 0.20929 kJ 100 calories to kJ = 0.41858 kJ 200 calories to kJ = 0.83716 kJ 500 calories to kJ = 2.0929 kJ 1000 calories to kJ = 4.1858 kJ Want other units?
