If you want to be pedantic (which I'm always accused to being
) 1 kilocalorie (what we wrongly call a calorie) is equal to 4.1868 kilojoules.
I use a program call Convert for all my convertions, hard to use if you are out and about though, but I love it.
You can convert anything to anything with it, so long as they are the same thing that is. eg: mass, energy, volume, area, etc. It's great.
It's a free program that my dad came across a while ago.
You can download it HERE
, if anyone is interested that is.
