Now I'm used to seeing values in articles, books, diets etc given in calories.. but here food packaging seems to use kcal, as in kilocalories. I think they are interchangable, perhaps due to the fact I live in the UK, because otherwise that would suggest a single bowl of cereal contains 200kcal, or 200,000 calories? 
So are these both terms for the same value of energy, or is there some conversion to be done, as per the metric/imperial system.
Thanks.
