How reliable is the source data for Cheese? Cheese uses USDA FoodData Central Foundation Foods as the nutrition source, FDC ID 746767. Gram-based calculations use the per-100g source values, while cup and spoon estimates depend on the listed density and should be treated as practical serving estimates.

Should I measure Cheese raw or cooked? Cheese should be logged in the same prep state as the source record. If you weighed it cooked, avoid comparing it directly with a raw entry unless a cooked yield factor is available.

Why Volume ≠ Weight: Cheese Density Explained

Cheese is dense (~1000 kg/m³ ≈ water). A 1-cup measure holds approximately 237 g.

Why does density matter? The same volume can hold very different amounts of food depending on how dense it is. Oats (350 kg/m³) are light and airy — 1 cup = ~80 g. Water has a density of 1000 kg/m³ — 1 cup = 236 g. This is why nutrition labels use weight (grams), not volume — it's a more reliable measure.

Formula: mass (g) = volume (mL) × density (kg/m³) ÷ 1,000. This calculator uses this formula automatically when you enter a volume measure for Cheese.

Data Sources & Methodology

Data source: USDA FoodData Central. Referenced entries: Cheese, Swiss (FDC ID: 746767).

Computation method: Macro values are calculated by multiplying the food's per-100g value by the requested weight in grams, then dividing by 100. Volume inputs are first converted to grams using the food's density (kg/m³) from USDA data, then the same formula applies: calories = (weight_g / 100) × caloriesPer100g.

Accuracy note: Macro values represent averages across measured samples; individual items may vary ±5–10% depending on brand, farming method, and preparation technique. For clinical nutrition, consult a registered dietitian.

Update policy: Macro values are reviewed quarterly against USDA FoodData Central updates. Page last verified: 2026.
