Convert kilocalories (kcal) to kilojoules (kJ) with formulas, examples, and conversion tables.
To convert 1 kilocalories to kilojoules, we multiply by 4.184 because one kilocalorie equals exactly 4.184 kilojoules.
Since each kilocalorie contains 4.184 kilojoules, we multiply our value by this factor:
So 1 kilocalories = 4.184 kilojoules.
To convert kilocalories to kilojoules, multiply the value by 4.184.
1 kilocalorie = 4.184 kilojoules
