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: 
http://www.aprioriathletics.com/calculators/unitconverter/energy.htm )


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?"
http://www.weight-loss-program.com/art02-what-is-calorie.html )


KJ stands for Kilojoules per mole or "Joule." How Stuff Works says: "A
food calorie contains 4,184 joules." ("How Calories Work:"
http://health.howstuffworks.com/calorie1.htm )

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

Kind regards,

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
milligrams!).

A calorie is equal to 4.2 kilojoules as explained in this site:
http://www.formulaforlife.com.au/asp/healthyliving.asp?section=nutrition&subsec=calories&pg=index

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".
