How it works
Enter a value, select Kilocalorie and Kilojoule, then MimiFile calculates the result instantly using the conversion model for this category.
Convert kilocalories (kcal) to kilojoules (kJ), including the two energy units commonly shown together on nutrition labels.
Enter a value, select Kilocalorie and Kilojoule, then MimiFile calculates the result instantly using the conversion model for this category.
Multiply kilocalories by exactly 4.184 to get kilojoules. For example, 500 kcal = 2092 kJ and 2000 kcal = 8368 kJ.
Energy uses a base-unit scale model.
kJ = kcal × 4.184 because MimiFile's registry defines 1 kcal as exactly 4184 J and 1 kJ as exactly 1000 J.
A kilocalorie (kcal) is the unit commonly called a food Calorie with a capital C. It is 1000 small thermochemical calories (cal).
Useful when a specification, map, recipe, technical document or device uses Kilojoule while your source value is in Kilocalorie.
