1 kilojoule in kilocalorie

1 kilojoule is 0.239006 kilocalorie 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 kilojoule = 0.239006 kilocalorie, so 1 kilojoule always maps to 0.239006 kilocalorie until you change the input. The reverse figure is 1 kilocalorie ≈ 4.184 kilojoule.
