Required fields: name, kJ, carbs, fat, protein. You must state the units of measurement that are being used, except for kJ, which is in kilojoules (1 Calorie = 1 kcal = 4.2 kJ). The units are usually expressed in grams (g), for example: |fat=3 g. Note: To specify energy in kcal rather than kJ, use kcal instead.
Default serving size ("100 g" for the standard 100 g serving size). calories: Calories per serving. Use a raw number for automatic conversion to kJ. calories_ref: Citation for the calories per serving. protein: The amount of protein in the dish per serving. fat: The amount of fat in the dish per serving. carbohydrate
The precise equivalence between calories and joules has varied over the years, but in thermochemistry and nutrition it is now generally assumed that one (small) calorie (thermochemical calorie) is equal to exactly 4.184 J, and therefore one kilocalorie (one large calorie) is 4184 J or 4.184 kJ.
Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [ 2 ] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.
According to the FAO, the average minimum daily energy requirement is approximately 8,400 kilojoules (2,000 kcal) per adult and 4,200 kilojoules (1,000 kcal) a child. [3] This data is presented in kilojoules, as most countries today use the SI unit kilojoules as their primary measurement for food energy intake, [ 4 ] with the exception of the ...
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.
