<P> The calorie equals the amount of thermal energy necessary to raise the temperature of one gram of water by 1 Celsius degree , from a temperature of 14.5 degrees Celsius , at a pressure of 1 atm . For thermochemistry a calorie of 4.184 J is used , but other calories have also been defined , such as the International Steam Table calorie of 4.1868 J. Food energy is measured in large calories or kilocalories , often simply written capitalized as `` Calories '' ( = 10 calories ) . </P>
