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.

Chicken breast Protein — Frequently Asked Questions

How much protein is in 100g of Chicken breast? 100g of Chicken breast contains 31 g of protein (USDA FoodData Central). This is considered high-protein.

How much protein in one Chicken breast? A typical chicken breast (A medium chicken breast loses ~25% weight when grilled, leaving approximately 130g cooked.) weighs about 130g and contains 40.3 g of protein. This is calculated as 130g ÷ 100 × 31 = 40.3 g.

How much protein is in 1 cup of Chicken breast? One US cup of chicken breast weighs approximately 251g (density: 1060 kg/m³). That serving contains 77.8 g of protein — computed as 251g ÷ 100 × 31.

How many grams of Chicken breast do I need to eat to get 30 g of protein? To reach 30 g of protein from Chicken breast, you need approximately 97g — calculated as (30 ÷ 31) × 100 = 97g.

Is Chicken breast high in protein? Yes, Chicken breast is high in protein at 31 g per 100g. It ranks among the better sources in its category.

What percentage of daily protein does 100g of Chicken breast provide? 100g of Chicken breast provides 31 g of protein, which is 62% of the reference daily intake (50 g/day for adults, based on a 2000-calorie diet). To reach 100% of your daily protein from Chicken breast alone, you would need ~161g.

What are the most common mistakes when measuring Chicken breast protein? 1. 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). 2. Assuming all cooking methods are equal: grilling and baking yield similar macros; frying with oil adds significant fat.

How efficient is Chicken breast as a source of protein per calorie? Chicken breast provides 18.79 g of protein per 100 kcal, making it excellent as a protein-per-calorie source. This is useful for calorie-restricted diets where macronutrient density matters.

What formula does this Chicken breast protein calculator use? The calculator uses protein = weight in grams / 100 x 31 g. For example, 100g of Chicken breast gives 31 g of protein. Volume entries are first converted to grams using the food density value, then the same per-100g formula is applied.

Is Chicken breast a good food for muscle building or high-protein goals? For muscle building or high-protein goals, Chicken breast is an excellent choice — with 31 g of protein per 100g. Chicken breast is also keto-friendly, gluten-free, a high-protein option. For best results, combine Chicken breast with other foods to hit your daily macro targets.

How to Calculate Chicken breast Protein

Weigh raw. Place your chicken breast on a kitchen scale before cooking to get the most accurate starting weight.
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.
