How many grams in an ounce of cheese?

One ounce of cheese equals 28.35 grams, typically rounded to 28 g in nutrition labels. A standard USDA serving for hard cheese (cheddar, Swiss, parmesan) is 1.5 oz = approximately 42 grams. For soft cheeses like mozzarella or brie, the serving is also 1.5 oz (42 g).

How much is a serving of cheese in grams?

According to USDA MyPlate guidelines, one serving of hard cheese (cheddar, Swiss, parmesan) is 1.5 oz = 42 grams. One serving of soft cheese (mozzarella, brie) is also 1.5 oz = 42 grams. For cream cheese, the serving is 2 tablespoons = 29 grams. These servings each count as approximately one dairy equivalent.

How many cups is 100g of shredded cheese?

For shredded cheddar, 100 grams is approximately 0.88 cups (just under 1 cup). One cup of loosely packed shredded cheddar weighs about 113 grams. Note that packing density significantly affects this — firmly packed shredded cheese can weigh 30–40% more per cup than loosely measured.

Cheese Portion Guide: Serving Sizes in Grams, Oz & Cups

Standard Cheese Serving Sizes

The USDA MyPlate guidelines define one dairy serving as 1.5 oz of hard natural cheese or 2 oz of processed cheese. These amounts are based on calcium content — a single 1.5 oz serving of cheddar delivers roughly 300 mg of calcium, approximately 23% of the Daily Value. The conversion from ounces to grams is always: 1 oz = 28.35 g.

Cups to Grams: Shredded and Crumbled Cheese

Volume measurements for cheese are unreliable because shredded and crumbled cheeses have very different packing densities. Finely grated parmesan is much denser than loosely shredded mozzarella. The values below assume standard loose packing — scooping without pressing down.

Cheese	1 Cup (g)	½ Cup (g)	¼ Cup (g)	Notes
Shredded cheddar	113 g	57 g	28 g	Fine shred; coarse shred ~100 g/cup
Shredded mozzarella	113 g	57 g	28 g	Low-moisture part-skim
Grated parmesan	100 g	50 g	25 g	Fine-grated; canister style ~80 g/cup
Crumbled feta	150 g	75 g	38 g	Denser due to moisture content
Crumbled blue cheese	135 g	68 g	34 g	Varies by moisture
Shredded Gruyère	110 g	55 g	28 g	Similar to cheddar

Tips for Accurate Cheese Measurement

For recipes where cheese quantity matters (pasta sauces, cheesecakes, calorie tracking), always measure by weight rather than volume. A kitchen scale set to grams gives the most consistent results. If measuring by cup, use the spoon-and-level method: spoon the shredded cheese into the measuring cup without pressing, then level off with a straight edge.

Pre-shredded bags contain anti-caking agents (e.g., potato starch) that add slight volume and weight
Freshly grated cheese from a block is denser than pre-shredded for the same cup volume
Aged hard cheeses (aged cheddar, aged parmesan) lose moisture, making them denser per ounce
For pizza: most recipes use 4 oz (113 g) shredded mozzarella per 12-inch pie
