Every 100 kcal of milk (2%) brings 6.6 g of protein. On that measure it ranks 33rd of the 81 dairy foods in this database and 373rd of all 796 foods on the site. Measured by weight instead, its 3.3 g per 100 g ranks 73rd in its group.
Around 26% of the calories in milk (2%) come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Weight for weight, milk (2%) has 1.7 g of protein for each gram of fat (3.3 g against 1.98 g per 100 g).
Set against swiss cheese, another dairy food entry in the database, a serving carries about 0.5 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 quoted here is measured by volume at 244 g, and it covers about 16% of the 50 g FDA Daily Value for protein.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
3.3 g. The 1 cup serving used on this page weighs 244 g and so carries 8.1 g.
How much protein do you get per 100 calories of milk (2%)?
6.6 g. That figure divides its 3.3 g of protein per 100 g by its 50 kcal per 100 g, so it does not depend on serving size.
Is the protein in milk (2%) complete?
Yes. The protein in milk (2%) supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own.
What share of the protein Daily Value is one serving of milk (2%)?
About 16%. One 1 cup serving has 8.1 g, and the FDA Daily Value for protein is 50 g.
