    I agree with @God on this. Another is that is was a very terrible idea and way to measure energy potential in food.

    That is why scientists veered away from calories and use joules instead. Also joules gives a more accurate results.

    A calorie is a unit of measurement of energy. 

    A Calorie is also called a kilocalorie and is 1,000 calories. 

    If the last sentence doesn't make sense,  I am sorry grammar wasn't a part of your education.

    They are a measure of heat energy...either actual heat or heat potential.  So when we talk about calories in food, we are describing how much heat potential that food has.  

    BTW, just to make it really confusing, the food calories are actually KILOcalories...thousands of calories.  So if that chocolate sundae has 1000 calories packed in it it really has the potential (as processed food) to develop 1000 thousand physical calories which are the calories used in physics and engineering.

    To give you a feel for the size of a calorie 14.5 calories is the equivalent heat per second of a 60 Watt light bulb.

    A calorie is a unit of heat.  The amount of heat it takes to raise the temperature of one gram of water one degree Celsius is a calorie.
