20 kilocalories in kilojoule

20 kilocalories is 83.68 kilojoule using the standard food-energy factor on NiftyRecipe.

Package labels, recipe macros and fitness apps often jump between kilocalories and smaller calorie units (or kilojoules). Here the ratio stays constant: 1 kilocalorie = 4.184 kilojoule, so 20 kilocalories always maps to 83.68 kilojoule until you change the input. The reverse figure is 1 kilojoule ≈ 0.239006 kilocalorie.
