You have to be careful about what you mean by calorie, as there are two kinds. The standard calorie (the energy it takes to raise 1 cc of water 1ºC) is 4.185 joules. However the calorie used to depict the energy content of food is the "large Calorie", spelled with a capital "C", and is equal to one kilocalorie and therefore 4.185 kilojoules.

If you are talking physics then:
1 calorie = 4.186 Joules.
The "calories" that people count in their diets, food etc, are not calories, but kilocalories.
1 "food calorie" = 1000 calories = 4186 Joule.
