The milk from bovines has a standardized density of 1.04 milligrams. However, air temperature and breed of cow can affect the density of milk.
Milk's density is made up of its primary components. Milk has 21.25 calories per 3.5 ounces. It also has 17.4 calories per 100 grams while the protein content measures up to 16.8 calories per 3.5 ounces. The remaining 0.48 calories per 3.5 ounces are the impurities present in the 56 calorie total. As a result, milk has a small difference between the greater milligram density and lesser milliliter density. The figure is not absolute with range usually measuring between 0.02 milligrams difference and 0.06 milligrams difference. All calculations are for density at room temperature. Changing the ambient temperature will alter the density of the milk.
