Parmesan serving size: 2 tsp (5g). FDA files parmesan under “Cheese, grated hard, e.g., Parmesan, Romano”, whose reference amount customarily consumed (RACC) is 5 g. The serving on your Nutrition Facts panel is the household measure closest to that reference amount, written as the measure followed by its metric weight.
The gram weight in parentheses assumes a typical density for parmesan (0.42 g/mL). Your own product’s weight of 2 tsp is what goes on the label; the app asks you to weigh one cup so the number is yours, not an estimate.
The declaration
| FDA category | Dairy Products and Substitutes: Cheese, grated hard, e.g., Parmesan, Romano |
| Reference amount (RACC) | 5 g |
| FDA label statement | __ tbsp (__ g) |
| Serving size declaration | 2 tsp (5g) (gram weight estimated, weigh to confirm) |
| Single-serving container | Any package under 10 g (0.4 oz) is one serving: the whole package is the serving size (21 CFR 101.9(b)(6)). |
| Dual-column panel | Packages holding 10 g–15 g (0.4 oz–0.5 oz) must show a second column for the whole package (21 CFR 101.9(b)(12)). |
Servings per container
| Package | Serving size | Servings per container |
|---|---|---|
| 8 oz (227 g) | 2 tsp (5g) | about 45 |
| 12 oz (340 g) | 2 tsp (5g) | about 68 |
| 16 oz (454 g) | 2 tsp (5g) | about 91 |
| 24 oz (680 g) | 2 tsp (5g) | about 136 |

Servings are rounded exactly as 21 CFR 101.9(b)(8) requires: to the nearest whole number, except between 2 and 5 servings, which round to the nearest half; “about” marks any rounding.
What this means for your label
- Declare the serving as 2 tsp followed by its weight in grams, for example “2 tsp (5g)”.
- Cups are written in 1/4- or 1/3-cup steps; tablespoons as 1, 1 1/3, 1 1/2, 1 2/3, 2 or 3; teaspoons as 1/8, 1/4, 1/2, 3/4, 1 or 2 (21 CFR 101.9(b)(5)(i)). Any other increment is not permitted.
- A package under 10 g is one serving no matter what: the panel reads “1 serving per container” and the serving size is the whole package.
- All the nutrient values on the panel are per this serving, rounded by 21 CFR 101.9(c). Change the serving and every number changes with it.
