kilo joules are used but sometimes calories are also used.
Kilo joules are used to measure the amount of energy stored in food.
Calories are the unit of energy used to measure how much energy is present in food. One calorie is the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.
The recommended unit to use for any type of energy is the joule. That way, no conversion factors are required, when converting from one type of energy to another. In practice, the calorie or kilocalorie is still sometimes used for food.
A calorie is a unit of heat used to measure the energy your body uses and the energy it receives from food. It represents the amount of energy required to raise the temperature of one gram of water by one degree Celsius.
Calorie is the unit used to express chemical energy in food.
The unit of measurement used to measure the amount of heat produced during metabolism is kilocalorie (kcal). This unit is commonly used to quantify the energy content of food as well.
Calories are a unit of energy that measure the amount of energy in food. Density, which is the amount of mass per unit volume of a substance, is not directly related to the measurement of calories. Calories in food are typically measured based on the macronutrients it contains, such as carbohydrates, fats, and proteins.
Any unit of energy can be used to describe the energy content of food.
A kilocalorie is not a measure of weight. It is a measure of energy
The unit to measure the amount of electrical energy is the kilowatt-hour (kWh). It is commonly used by utility companies to bill customers for electricity consumption.
answer:A calorie is a unit of measure used to describe the energy in food. It is defined as the amount of heat required to raise the temperature of 1kg of water 1 degree Celsius at 1 atmosphere pressure, or 4.184 Joules.Another AnswerA calorie is an obsolescent unit of measurement (cgsA system) used to measure energy; it is not simply used to measure the energy available in food, as implied by the original answer. It was defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.The original answer is not describing a calorie, but a kilocalorie which is 1000 calories.
Wrong. The calorie is not an SI unit, and it is confusing because it comes in two varieties: gram when spelled calorie (small c) and Kilogram when spelled Calorie (Capital C). The SI energy unit is the Joule.
