The fat content of milk is the proportion of milk, by weight, [1]: 266 made up by butterfat. The fat content, particularly of cow 's milk, is modified to make a variety of products. The fat content of milk is usually stated on the container, and the color of the label or milk bottle top varied to enable quick recognition.
Commercial products generally contain the minimum legal amount of fat with any excess being removed to make cream, a valuable commodity. Milks.

Full fat milk contains about 33 grams of fat per liter, including about 19 grams of saturated fat, 1.2 grams of omega 6 fatty acids, and 0.75 grams of omega 3 fatty acids per liter. The amount of fat varies for products where (some of) the fat has been removed, such as in skimmed milk. [92]
Of that weight, 2% milk holds 5 grams of fat and whole milk contains 8 grams. So whole milk isn't much fattier than 2%. In fact, a gallon of 2% has more than half the fat as a gallon of whole milk ...

The test is based on the observation that a suitable amount of sulfuric acid added to the milk will dissolve proteins and other components, except the fat. Heating and centrifuging cause the fat to separate and float to the top, in a layer free of bubbles. The amount of fat in the milk can then be estimated from the volume of that layer.
