Calories are HEAT energy...that's why when you burn them (like when you exercise) you get hot. You are always burning calories.....btw....that Courtny T person.....it takes 1 calorie to heat up 1 mL (not kg) by 1 degree

A calorie is a unit of energy. The Calories on food (note the capital C) actually represent 1000 calories. One food calorie is enough energy to raise on liter of water one degree celcius.


littleloudboy2
Well this is how I see calories. Calories mean to me energy. Example: would be everytime you stroke a key on the keyboard you are wasting calories and when you go jogging you lose calories. So that means all they are is energy. More calories you have more energy usually but if you have to many calories and dont exercise or do any sort of activity they will turn into fat.

How in the world could 125 people be answering such a painfully simple question?! This is insane and rediculous! This is like asking what is a rock or what is a phone or why do I need to breathe.

What is a calorie..... Man alive. If you really need to know, eat a big chocolate cake and take a look into the mirror at your rear end and all of your questions will be answered.

1 calorie is the amount of energy needed to raise 1ml of water by 1C

We use calories as a unit of how much energy is in our food.

A simple test for energy in food is to burn it, the longer it burns the more energy.

Calories are a measure of energy. Most people need around 1200-2500 a day depending on your height, weight, metabolism, gender, and how active you are. If you consume more calories than you need, you will gain weight; if you burn more calories than you consume, you will lose weight.

Calories are one of the measuring units of heat. The standard measuring unit is Joules. 1 cal = 4.18 joules. also 1 cal is equal to the amount of heat required to raise 1g of water through 1 deg C.

A calorie is a unit used to measure energy or more specifically heat. The quantity of heat required to raise the temperature of 1 gram of water by 1°C from a standard initial temperature, especially from 3.98°C, 14.5°C, or 19.5°C, at 1 atmosphere pressure.

A calorie is a unit of measurement for energy. The unit's name is French and derives from the Latin calor (heat). In most fields, it has been replaced by the joule, the SI unit of energy. However, it remains in common use for the amount of energy obtained from food. Many different definitions for the calorie emerged during the 19th and 20th centuries. They fall into two classes:

* The small calorie or gram calorie approximates the energy needed to increase the temperature of 1 g of water by 1 °C. This is about 4.184 J.
* The large calorie or kilogram calorie approximates the energy needed to increase the temperature of 1 kg of water by 1 °C. This is about 4.184 kJ, and exactly 1000 small calories.

In scientific contexts, the name "calorie" refers strictly to the gram calorie, and this unit has the symbol cal. SI prefixes are used with this name and symbol, so that the kilogram calorie is known as the "kilo calorie" and has the symbol kcal.

Colloquially, and in nutrition and food labeling, the term "calorie" almost always refers to the kilogram calorie. This applies only to English text; if an energy measurement is given using a unit symbol then the scientific practice prevails there. A convention of capitalizing "Calorie" to refer to the kilogram calorie, with uncapitalized "calorie" referring to the gram calorie, is sometimes proposed, but neither recognized in any official standards, nor commonly followed.

The conversion factor between calories and joules is numerically equivalent to the specific heat capacity of liquid water (in SI units).

You get energy from eating food. Calories is the measure of how much energy is stored in that food.

Well, don'cha learn something new every day. I never knew that a food calorie was 1 000.669 216 061 thermochemical calories. It does seem to fit the scale of the human body much better, though. Instead of the amount of energy it takes to raise 1/28th of an ounce one degree celsius, we're talking about the amount of energy it takes to raise one kilogram by one degree celsius. So if a person weighs 75 kilograms (165 pounds) and eats 2000 food calories, that's enough energy to raise his body temperature by 27 degrees celsius (if it did so all at once). A reasonable amount and two things occur to me. One is how magnificently efficient the body is at using energy. The other is that it's so efficient that it's easy to overload on fuel and store it, whether we want to or not.

Specifically, a calorie is the amount of energy, or heat, it takes to raise the temperature of 1 gram of water 1 degree Celsius (1.8 degrees Fahrenheit). One calorie is equal to 4.184 joules, a common unit of energy used in physical science.

well..! a calorie is the amount of energy. a calorie is equal to about 4.1 joul.

joul in physics is defined as: the amount of energy required to produce an acceleration of
1m/s in an object of 1kg OR
the amount of energy required to increase the temp. of 1grm water from 14.5c* to 15.5c*

note: now it is neccessary to know that the word calorie actually we use in our daily life is
in reall k.cal. but k is not used.
a k.calorie is equal to 1000 calories
k.calorie can be written as Calorie .without k
but cappital C Clorie=1000 calorie

A calorie is the amount of heat required to raise one gram of water one degree Centigrade. The caloric content of food stiffs is a measure of their heat content and is expressed in Kilo calories. One gram of protein or carbohydrate contains 4 calories and one gram of fat 9 calories.


Richard H
a calorie (notice the SMALL C) is the amount of energy that it takes to increase the temperature of one gram of water by one degree Centigrade (also called Celsius). A Calorie (notice the big C), also called a "Kcal" is 1,000 of the SMALL C calories. When you count Calories, you are counting KCals, not calories.

a calorie is a unit of energy. 1 calorie is the amount of energy that is needed to heat 1 gram of water 1 degree Celcius.

however despite what most people think, a food calorie is actually a kilocalorie (1000 calories = 1 kilocalorie) so this can of soda sitting in front of me has 140 kilocalories or 140,000 calories.

A calorie is a unit of energy (such as a watt in a lightbulb) in food. If a food has 100 calories, it contains 100 units of energy. Depending on your gender and BMI, most healthy adults should take in 1200-2000 cal per day because your body needs a certain number of cal per day just to run itself, even if youre sitting on the couch.

A calorie is a unit of energy. We tend to associate calories with food, but they apply to anything containing energy. For example, a gallon (about 4 liters) of gasoline contains about 31,000,000 calories.

Specifically, a calorie is the amount of energy, or heat, it takes to raise the temperature of 1 gram of water 1 degree Celsius (1.8 degrees Fahrenheit). One calorie is equal to 4.184 joules, a common unit of energy used in the physical sciences.

Most of us think of calories in relation to food, as in "This can of soda has 200 calories." It turns out that the calories on a food package are actually kilocalories (1,000 calories = 1 kilocalorie). The word is sometimes capitalized to show the difference, but usually not. A food calorie contains 4,184 joules. A can of soda containing 200 food calories contains 200,000 regular calories, or 200 kilocalories. A gallon of gasoline contains 31,000 kilocalories.

The same applies to exercise -- when a fitness chart says you burn about 100 calories for every mile you jog, it means 100 kilocalories.
