A typical 1 oz serving of cheddar cheese contains 6.4 grams of protein (22.9 g per 100 g), which makes it a moderate source of protein. That covers roughly 13% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 23% of the calories in cheddar cheese 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.
Among the 81 dairy foods in the database, cheddar cheese ranks 54th by protein per serving, and 414th out of all 796 foods on the site. Set against yogurt (whole milk, plain), another dairy food entry in the database, a serving carries about 0.5 g more protein (yogurt (whole milk, plain) has 5.9 g per 1 container).
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 weight at 28 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
