Every 100 kcal of half and half brings 2.4 g of protein. On that measure it ranks 77th of the 81 dairy foods in this database and 657th of all 796 foods on the site. Measured by weight instead, its 3.13 g per 100 g ranks 77th in its group.
Only about 10% of the calories in half and half come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
By weight, fat outweighs protein in half and half: 11.5 g of fat per 100 g against 3.13 g of protein, a ratio of 0.3 to 1.
Set against sweet whey powder, another dairy food entry in the database, a serving carries about 0.5 g less protein (sweet whey powder has 1 g per 1 tbsp).
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 15 g, and it covers about 1% of the 50 g FDA Daily Value for protein.

Per-100 g values are the amino acid analysis on the USDA record. The serving and per-gram-of-protein columns are arithmetic on those values; they are not a protein quality score.

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.
3.13 g. The 1 tbsp serving used on this page weighs 15 g and so carries 0.5 g.
How much protein do you get per 100 calories of half and half?
2.4 g. That figure divides its 3.13 g of protein per 100 g by its 131 kcal per 100 g, so it does not depend on serving size.
Is the protein in half and half complete?
Yes. The protein in half and half 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 half and half?
About 1%. One 1 tbsp serving has 0.5 g, and the FDA Daily Value for protein is 50 g.
