look up any word, like bae:
 
3.
a mythical unit that is used to make people think they will get fat from eating certain foods.
a 1"x1"x1" piece of cheese cake has 690 calories which makes you a fatass if you eat it, but an entire bowl of salad has 6.9 calories which makes you a healthy eater; thus the reason why its a myth.

1.
A measure of heat, equal to the amount of energy required to raise one gram of water by one degree Celsius. Not to be confused with the food Calorie (capital C), which is equal to 1 kilocalorie (1000 calories), or the amount of energy required to raise one kilogram of water by one degree Celsius.

1 calorie = 4.184 joules
When people talk about the amount of calories they get from food, they are really referring to Calories, or kilocalories.
