Real-World Chicken breast Serving Sizes
- 1 small chicken breast (~120g): 144 kcal calories. A small chicken breast, common in budget packs, weighs about 120g raw.
- 1 medium chicken breast (~174g): 208.8 kcal calories. A standard supermarket chicken breast weighs approximately 174g raw - the most common size.
- 1 large chicken breast (~220g): 264 kcal calories. A large restaurant-portion chicken breast weighs around 220g raw.
- 1 cup diced (raw) (~140g): 168 kcal calories. One US cup of raw chicken breast, diced into 2cm cubes, weighs approximately 140g.
Common Chicken breast Measurement Mistakes
- Weighing chicken after cooking instead of before: 100g cooked ≠ 100g raw. Chicken loses ~25% weight when grilled, so cooked protein concentration rises to ~30g/100g.
- Assuming 1 cup equals 100g: 1 cup of diced raw chicken breast weighs approximately 140g, not 100g.
- Ignoring prep state in a macro tracker: log raw weight if you weighed it raw, or switch the tracker entry to cooked.

How efficient is Chicken breast as a source of calories per calorie? Chicken breast provides 100 kcal of calories per 100 kcal, making it excellent as a calories-per-calorie source. This is useful for calorie-restricted diets where macronutrient density matters.
What formula does this Chicken breast calories calculator use? The calculator uses calories = weight in grams / 100 x 120 kcal. For example, 100g of Chicken breast gives 120 kcal of calories. 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 weight gain or calorie surplus goals? For weight gain or calorie surplus goals, Chicken breast is a modest contributor — with 120 kcal of calories 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 reliable is the source data for Chicken breast? Chicken breast uses USDA FoodData Central reference as the nutrition source, FDC ID 331960.

How to Calculate Chicken breast Calories
- 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.

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 (raw)" = 140 g (One US cup of raw chicken breast, diced into 2cm cubes, 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, raw (FDC ID: 331960).
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.
