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.
No, kilocalories measure the amount of energy in foods. There is between 4 and 9 kilocalories per gram in the digestible portion of any foods.
Those are different types of energy, but energy nonetheless. You can express any type of energy (in the sense that the word "energy" is used in physics) in calores. Please note, however, that the preferred unit is the joule.
Calories are the standard unit.
how much energy the food molecules have
A calorimeter. Basically you burn food inside a box and then measure the energy you get out of it. You have to make sure that the energy does not get out of the box
The amount of energy that you can get from that food. We get our energy from calories. And when we burn energy, we burn calories. So, we measure calories to see how much energy we will get from that particular food. This tells us how much of that food we should eat, compared to how much energy we expend.
The amount of oxygen that's consumed when you burn your food is an indirect measure of the amount of energy that's released from the food. Bomb calorimeters are sometimes used to measure the energy content in food.
Do you mean a calorie? A calorie is a unit used for measuring the amount of energy in food.
Kilo joules are used to measure the amount of energy stored in food.
by burning it, and measuring the calories burned.
Cal means calories. It is a measure of the amount of energy that a particular food has. So, if we eat that particular food, then we will obtain that amount of energy.
No, kilocalories measure the amount of energy in foods. There is between 4 and 9 kilocalories per gram in the digestible portion of any foods.
depends on why you are measuring it... if you are measuring to know how much food it can hold, measure inside.
You can measure its volume with a measuring cup or measuring spoons. You can measure its weight with a food scale. You can measure its temperature with a thermometer.
There isn't a "herbal energy" in the strict sense of 'energy' but it may be a measure of the energy you'd obtain from a given amount of a herbal tea or similar as a food.
A scale.
Calories are not a nutrient,they measure the amount of energy the food has. That said, they are in a way essential because no calories means no energy that food gives your body. Your body needs food for life sustainance
