GRAM CALORIE Meaning and
Definition
-
A gram calorie, also referred to as a small calorie, is a unit of energy measurement within the field of physics and thermodynamics. It is used to quantify the amount of heat or energy required to raise the temperature of one gram of water by one degree Celsius or one Kelvin. The gram calorie is often used in scientific discussions to represent the energy content of food or the energy expended during physical exercises.
The gram calorie is equivalent to approximately 4.184 joules in the metric system. However, it should be noted that the gram calorie is a relatively small unit of energy, which is why it is more commonly used to discuss the energy content of food on a per-gram basis rather than overall energy calculations.
In the context of human nutrition, the gram calorie is frequently utilized to measure the caloric content of specific macronutrients, such as carbohydrates, proteins, and fats. For example, one gram of carbohydrates or proteins contains about 4 gram calories, while one gram of fat contains approximately 9 gram calories.
It is important to differentiate the gram calorie from the larger unit of energy measurement known as the kilocalorie, commonly referred to as a Calorie. One kilocalorie is equal to 1,000 gram calories, and the Calorie is the unit typically used to express the energy present in food.
