https://en.wikipedia.org/wiki/Calorie
The calorie is a unit of energy. The Calorie (note the capital C) is 1,000 calories.
The Calorie (large calorie or kilocalorie - symbols: Cal, kcal), also known as the food calorie
The word calorie is popularly used with the number of kilocalories of nutritional energy measured. As if to avoid confusion, it is sometimes written Calorie (with a capital "C") in an attempt to make the distinction, although this is not widely understood.
