Find the conversion factor from Kilocalorie (food Calorie) to Kilojoule
1 kcal = 4,184 J · 1 kJ = 1,000 J
factor = 4,184 ÷ 1,000 = 4.184 kJ per kcal
Multiply by the factor: kcal cancels, leaving kJ
kJ = kcal × (kJ per kcal)
1 kcal × 4.184 kJ per kcal = 4.184 kJ
How it works
1 kcal = 4.184 kJ, so kJ = kcal × 4.184
