Calories/kcal/Cal Kilojoules/kJ
10 42
50 209
100 418
250 1046

How do you calculate kilojoules?

Calculating energy changes

  1. = 100 × 4.2 × 20 = 8,400 J.
  2. It is also useful to remember that 1 kilojoule, 1 kJ, equals 1,000 J.
  3. Moles of propane burned = 0.5 ÷ 44 = 0.01136.
  4. So, the molar enthalpy change, ∆H = 8.4 ÷ 0.01136 = 739 kJ/mol.

How much is 2000 calories in kJ?

One calorie (kilocalories) is 4.18 kilojoules. Or to put it differently, 1kcal = 4.18kj. This therefore means that to convert 2000kcal into kilojoules, you would multiply 2000kcal by 4.18. This would make it 8,360kj.
