If the “c” in calories is uppercase, it indicates a large calorie, and if it’s lowercase, it indicates a small calorie. A large calorie estimates the amount of energy required to raise the temperature of 1 kg (2.2 pounds) of water by 1°C (or an increase of 1.8°F) (1Trusted Source). On the other hand, a small calorie estimates the amount of energy it takes to raise the temperature of 1 gram (0.035 ounces) of water by 1°C (or an increase of 1.8°F) (1Trusted Source). By these definitions, 1 large calorie equals 1,000 small calories, as 1 kg equals 1,000 grams. To avoid confusion between large and small calories, it’s thought that the term kilocalorie - the prefix “kilo” meaning 1,000 - was created to refer to a large calorie (1Trusted Source). However, the term small calorie is rarely used today outside of physics and chemistry research. Instead, the terms calories - capitalized or not - and kcal are used interchangeably and refer to the same amount of energy in relation to food or energy burned with exercise. Therefore, you don’t need to convert them, as 1 kilocalorie equals 1 calorie in nutrition.
