I'm sorry... but I thought a calorie was just a unit to measure energy... you know like a Joule... or a Pascal or a Watt..
Definition of a Calorie: The calorie equals the amount of thermal energy necessary to raise the temperature of one gram of water by 1 Celsius degree, at a pressure of 1 atm.
ETA: atm stands for atmospheres which is a unit of pressure.
Yes, but is an atmosphere and atmosphere? I guess that's an entirely different thread.
