Why Volume ≠ Weight: Peanut butter Density Explained
Peanut butter is dense (~1050 kg/m³ ≈ water). A 1-cup measure holds approximately 248 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 Peanut butter.

Data Sources & Methodology
Data source: USDA FoodData Central.
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.
