weight of the can or tray in grams. To determine cups per day of a dry food, the density of the food in terms of grams per cup must be known. If that information is not provided as part of the calorie content statement as required under AAFCO model regulations, it can be calculated by dividing the kcal/cup value by the kcal/kg value, then multiplying the result by 1000 to give you g/cup. The pet's food allowance in g/d is then divided by g/cup to give you cups/d. There is no standard international cup size, in the United States of America, a standard measuring cup is 8 fluid ounces (approximately 237 mL) by volume, however in other countries, different volumes or weights of typical dry ingredients are used to determine a cup unit. | weight of the can or tray in grams.
