Convert calories (cal) to kilojoules (kJ) with formulas, examples, and conversion tables.
To convert 1 calories to kilojoules, we divide by 239.006 because one kilojoule equals exactly 239.006 calories.
Since there are 239.006 calories in every kilojoule, we divide our value by this factor:
So 1 calories = 0.004184 kilojoules.
To convert calories to kilojoules, divide the value by 239.006.
1 kilojoule = 239.006 calories
