As far as I know, they are the same thing. Either that or a calorie is infinitesimal. Kilocalories are what most refer to simply as calories (the calories listed on food labels.)
Answer
The clue is in the prefix, 'kilo'. A kilocalorie (kcal) is one-thousand calories (cal). The problem is that people in the food industry are either simply too lazy or too stupid to use the work 'kilocalorie'.
As the calorie is an obsolete unit, they should be using the joule.
The difference between a calorie and a Calorie is calorie is a smaller unit than Calorie and it takes 1000 calorie's to make a Calorie. The Calorie (kilocalorie, kcal) is 1000 calories - a more useful unit and widely used.
Its a calorie
A nutritional Calorie is 1000 times a chemical calorie.
The Calorie.
a scientific name for a calorie is a kilo calorie
The small calorie is equivalent to 4.2 joules. This is the scientific calorie, and it is usually replaced with units in joules. The kilogram calorie is the dietary or nutritional calorie. It is the equivalent of 4.2 kilojoules, 1000 times greater than the small calorie.
I believe that the Scientist's calorie is an actual calorie; however, the dietitian's calorie is actually a Kilo-calorie. In other words, although a box of cereal may say 100 calories/serving...this is not accurate. It should read either 100 Kcal/serving, or 100,000 calories/ serving, but that would be a bit overwhelming. So, we've adopted a system of Kilo-calories that we inaccurately call 'calories'.
