Some authors recommend the spelling Calorie and the symbol Cal (both with a capital C) if the large calorie is meant, to avoid confusion; [8] however, this convention is often ignored. [6] [7] [8] In physics and chemistry, the word calorie and its symbol usually refer to the small unit, the large one being called kilocalorie (kcal).

For an overall efficiency of 20%, one watt of mechanical power is equivalent to 18 kJ/h (4.3 kcal/h). For example, a manufacturer of rowing equipment shows calories released from "burning" food as four times the actual mechanical work, plus 1,300 kJ (300 kcal) per hour, [16] which amounts to about 20% efficiency at 250 watts of mechanical output.
A nutritional Calorie is equivalent to a thousand chemical or thermodynamic calories (abbreviated "cal" with a lower case "c") or one kilocalorie (kcal). Because food energy is commonly measured in Calories, the energy density of food is commonly called "caloric density". [7]
Then subtract the number of calories you want to take in per day from this total caloric expenditure. It is usually recommended to choose a caloric deficit between 500 and 1000 calories per day for mild to moderate weight loss. This will achieve an average weight loss of about 0.5 to 1 kg per week.

A calorimeter constant (denoted C cal) is a constant that quantifies the heat capacity of a calorimeter. [1] [2] It may be calculated by applying a known amount of heat to the calorimeter and measuring the calorimeter's corresponding change in temperature.
