A typical 1 cup serving of milk (1%) contains 8.2 grams of protein (3.37 g per 100 g), which makes it a good source of protein. That covers roughly 16% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Protein accounts for roughly 32% of the calories in milk (1%), making it moderately protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Among the 81 dairy foods in the database, milk (1%) ranks 27th by protein per serving, and 344th out of all 796 foods on the site. Set against swiss cheese, another dairy food entry in the database, a serving carries about 0.6 g more protein (swiss cheese has 7.6 g per 1 oz).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is measured by volume at 244 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
