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.
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'!
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.
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.

What is the difference between calories with a capital c and calories with a lower case c?
A calorie is a unit of energy. We tend to associate calories with food but they apply to anything containing energy. a Calorie is associated with food. They are actually kilocalories, so 1 Calorie= 1000 calories
What is the difference between calorie and kilo calorie?
A calorie is a unit of energy and is often used to measure the energy content in food. A kilocalorie (kcal) is equal to 1000 calories and is commonly used to represent the energy content of food. So when you see calories listed on a food label, they are usually referring to kilocalories.
How much calories is in one calorie?
Assuming that you're talking about the difference between the calories listed on "Nutritional Information" labels on food, one "food calorie" is equal to 4.184 kilojoules, or 1000 calories in science (a "scientific calorie" being the amount of energy needed to raise one gram of water one degree Celsius).
Which energy is stored in energy and food?
calorie
What is a unit of food energy?
calorie--
A unit of energy in food?
A Calorie
How do you define 1calorie?
The large calorie, kilogram calorie, dietary calorie or food calorie approximates the energy needed to increase the temperature of 1 kilogram of water by 1 °C.
What is the difference between a Calorie on a food label and a calorie in science?
Both Calorie and calorie are measurements of energy. 1 Calorie = 1000 calories Upper-case Calorie is used in nutritional terms and is sometimes also referred to as a kilocalorie to avoid confusing it with the lower-case calorie. Please see the related link for more details The Calorie (kilocalorie, kcal) is 1000 calories - a more useful unit and widely used.
What is the difference between energy pyramid and food web?
the difference is that energy pyramids show life and food pyramids are just stacks of food
Energy in of food molecules is called?
calorie
What the definition of calorie?
