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.

What is a pound?

Pound, or avoirdupois pound (standard symbols: lb), is a unit of mass or weight in the UK imperial systems or the US customary systems of measurement. One pound equals 0.45359237 kilograms as legally defined in the international avoirdupois system or 16 avoirdupois ounces

Where does the term “pound” come from?

The term “pound” is derived from the Roman expression libra pondo, in which pondo means weight and libra (scale or balance) is a mass unit used in ancient Rome. 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.
