I am in Brazil...?!
Answers: Hi! I am in barra de tijuca rio de janeiro brazil, and all of the food has nutritional information in ′′kcals.′′ How do I know how many CALORIES are in it? Like what is the conversion rate? Thank you so much... = )
They are the same thing. It is just a different way of labeling it. They do that in Europe and most places outside US i think. You don't need to convert anything, ie 200 kcals is 200 calories.
Basically what we call a Calorie is actually 1000 'calorie units' on some scientific scale. So in some countries they call it a kcal -short for kilocalorie (kilo means a thousand). Pretty much we have just shortened it more in the US to plain old "calories". But kcal and calorie are the same thing just pretend the k isn't there.
This might help to explain the whole science part of it. What we use for food are the large calories, or kilocalories.

its pretty close to one for one but kcal to cal converter are available on-line. see one example below
