Hello shadow4444~

A kcal (kilocalorie) is the same as a food calorie. 

This can be confusing, as a calorie as used in nutrition is not the
same as a calorie used in science. "A food calorie is the same as a
kilocalorie...but a food calorie is not the same as a calorie (in
science)." (The WWW Unit Converter: )

Weight Loss Program also notes: "When speaking about food, we say
'calorie' when we mean 'kilocalorie'. For example, when you see '200
calories' on a food label, it actually means 200 kilocalories..."
("What Is a Calorie?" )

KJ stands for Kilojoules per mole or "Joule." How Stuff Works says: "A
food calorie contains 4,184 joules." ("How Calories Work:" )

If you like, you can automatically convert calories to KJ at EngNet:

Kind regards,

joules to food calories
convert kilocalories to calories

Kilojoules are simply the metric measure for calories. They're
standard use here in Australia and we don't generally use the term
"kilocalorie" at all (I guess it means a unit of one thousand calories
-- I've actually never heard the term used in everyday parlance)and a
joule is a far smaller unit of energy as to render it pointless in
cooking (a bit like measuring your 500 grams of flour as 50000

A calorie is equal to 4.2 kilojoules as explained in this site:

And this site offers a more in depth explanation of kJ as a unit of
energy as it relates to diet, metabolism and health:

Hope this helps.

Oh, and forgot to mention that the correct presentation is kJ (lower
case "k" and upper case "J".
