The calorie is a unit of energy that originated from the caloric theory of heat. [ 1 ] [ 2 ] The large calorie , food calorie , dietary calorie , or kilogram calorie is defined as the amount of heat needed to raise the temperature of one liter of water by one degree Celsius (or one kelvin ).
the small calorie (gram-calorie, cal) is 4.184 J exactly. It was originally defined so that the specific heat capacity of liquid water would be 1 cal/(°C⋅g). The grand calorie (kilocalorie, kilogram-calorie, food calorie, kcal, Cal) is 1000 small calories, 4184 J exactly. It was defined so that the specific heat capacity of water would be 1 ...
The typical energy released as heat by a person at rest every 1/60 s (~ 16.6667 ms, basal metabolic rate); about 5,000 kJ (1,200 kcal) / day. The amount of electricity required to run a 1 W device for 1 s. The energy required to accelerate a 1 kg mass at 1 m/s 2 through a distance of 1 m.
Heat 1/2 cup frozen berries in the microwave for 1 minute. Pour berries over yogurt-topped waffle and add 1 tablespoon chopped nuts. ... A 1,200-calorie meal plan doesn’t teach you how to handle ...
As the name suggests, a 1,200-calorie diet is a type of low-calorie diet plan that restricts daily caloric intake to approximately 1,200 calories a day, says Diala Alatassi, MD, a board-certified ...
The "grand calorie" (also "kilocalorie", "kilogram-calorie", or "food calorie"; "kcal" or "Cal") is 1000 cal, that is, exactly 4184 J. It was originally defined so that the heat capacity of 1 kg of water would be 1 kcal/°C. With these units of heat energy, the units of heat capacity are 1 cal/°C = 4.184 J/K ; 1 kcal/°C = 4184 J/K.

The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
