FAQ for kcal → cal
1 kilocalorie in calorie

1 kilocalorie is 1000 calorie 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 = 1000 calorie, so 1 kilocalorie always maps to 1000 calorie until you change the input. The reverse figure is 1 calorie ≈ 0.001 kilocalorie.

Use the field above to try another portion size, scale a recipe, or match two apps that print different units. Everything on this page stays inside nutrition-style energy units-no length, temperature or other measures mixed in.
