Real-World Chicken breast Serving Sizes
- 1 medium cooked chicken breast (~130g): 40.3 g protein. A medium chicken breast loses ~25% weight when grilled, leaving approximately 130g cooked.
- 1 cup diced (cooked) (~140g): 43.4 g protein. One US cup of diced cooked chicken breast weighs approximately 140g.
Common Chicken breast Measurement Mistakes
- Using raw chicken macros for cooked weight: if you weighed the chicken after cooking, select 'Chicken breast, cooked' - it has higher protein density (~31g/100g) than raw (~23g/100g).
- Assuming all cooking methods are equal: grilling and baking yield similar macros; frying with oil adds significant fat.

- Enter weight into the calculator. Select your unit (g, oz, lb, or cup) and hit Calculate.
- Read the result. The calculator shows protein content for your exact portion.
- Compare servings. Use the serving range table below to quickly compare protein across portion sizes.
- Log to your tracker. Enter the raw weight and raw entry in your nutrition app for consistent macro tracking.
Why Volume ≠ Weight: Chicken breast Density Explained
Chicken breast is dense (~1060 kg/m³ ≈ water). A 1-cup measure holds approximately 251 g. This aligns with the common culinary anchor: "1 cup diced (cooked)" = 140 g (One US cup of diced cooked chicken breast weighs approximately 140g.)
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 Chicken breast.

Data Sources & Methodology
Data source: USDA FoodData Central. Referenced entries: Chicken breast, cooked (FDC ID: 171477).
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: protein = (weight_g / 100) × proteinPer100g.
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.
