What are Calories (Cal, Kcal)?

The calorie is a unit of energy or heat. The calorie was at first defined as the amount of energy required to raise the temperature of 1 gram of water by 1°C. It is then redefined that 1 calorie is equal to approximately 4.2 joules because the amount of heat required to gain 1°C depends on the water temperature. 

The term “Calorie” may refer to “small calorie” (small calorie) or “large calorie” (kilogram calorie). The amount of energy needed to increase the temperature of 1 gram (g) of water by 1°C is known as a small calorie (cal). The amount of energy needed to raise one kilogram (kg) of water by 1°C is known as a large calorie (kcal) or kilocalorie. The latter is often found on package labels to show the amount of energy a specific food provides. When you see a food label that says 100 C or calories, it actually means 100 kcal or 100 kilocalories.

Where does the term “pound” come from?

That’s why the pound is abbreviated as lb. Nowadays, the pound as a unit of mass is commonly used in the United States and countries of the Commonwealth of Nations.
