What is the difference between a energy calorie and food calorie?

Answer 1

Calories can be broadly classified as

1.large calories

2.small calories

1. Large calories : This is also called as kilogram calorie, dietary calorie, nutritionist's calorie or food calorie.

"It is the energy required to increase the temperature of 1 kg of water by 1 degree C under 1 atmospheric pressure."

In conversion, 1kcal = 1 cal (in terms of large cal)

2. Small Calories : This is also called as gram calorie. (the other term you are refering in the question, 'calorie')

"It is the energy required to raise the temperature of 1gm of water by 1 degree C under 1 atmospheric pressure"

In conversion, 1Kcal = 1000 cal (interms of small cal)

So, when you are talking about 'calories', it refers to small calories.

And when you are talking about food calories or calories related to dietary facts, it refers to 'large calories', and remember the conversion holds.

Answer 2

A heat calorie is the amount of energy it takes to heat 1 mL of water 1 degree celsius.

A food calorie is 1000 heat calories. 1 food calorie is written as 1 C

Answer

A calorie is a calorie. Period! There is no such thing as a 'food calorie'! A calorie an obsolete unit from the cgsA system used to measure energy. Any form of energy. It is defined as the energy required to raise the temperature of one cubic centimetre of water by one degree Celsius.

The modern, SI, unit is the joule.

For some reason, the food industry can't get their head around the fact that they use kilocalories to measure the energy content of different foods. and not calories. The symbol for kilocalorie is 'kcal', NOT 'Calorie'!

Answer 3

A heat calorie is the amount of energy it takes to heat one gram of water one degree Celsius.

A food calorie is the amount of energy needed to heat 1000 grams of water 1 degree Celsius.

Answer 4

A calorie is simply a measurement of an amount of energy. A food calorie tells you how much energy is in a food. The biggest difference is that in nutrition, the word calorie is used as short for kilo-calorie (or 1,000 actual calories), whereas in physics or other forms of science, a calorie is simply a calorie.

Answer 5

There is no difference. Capitol letters do nothing.

Answer 6

One Calorie is equal to 1,000 calories.

Answer 7

They are the same.
