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.
A 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'.

A calorie is the unit of energy required to raise one gram of water 1 degree Celsius. A kilocalorie, or Calorie, is the equivalent of 1000 calories.

Both Calorie and calorie are measurements of energy. 1 Calorie = 1000 calories Upper-case Calorie is used in nutritional terms and is sometimes also referred to as a kilocalorie to avoid confusing it with the lower-case calorie. Please see the related link for more details The Calorie (kilocalorie, kcal) is 1000 calories - a more useful unit and widely used.
A calorie is essentially energy stored in the form of food. It takes one calorie to increase the temperature of 1 kilogram of water by 1 degree Celsius.
A nutritional Calorie is 1000 times a chemical calorie.
