Calories are a unit of measurement used to quantify the energy content of food and beverages. It is defined as the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius. Calories are commonly used to describe the amount of energy in food and are often used to track daily calorie intake for weight management and nutritional purposes. In nutrition, one calorie is equal to 4.184 joules. It is important to note that the term "calories" is often used interchangeably with "kilocalories" (kcal) in nutrition, where one kcal equals 1000 calories.
