Beef Protein — Frequently Asked Questions

How much protein is in 100g of Beef? 100g of Beef contains 23.7 g of protein (USDA FoodData Central). This is considered high-protein.

How much protein is in 1 cup of Beef? One US cup of beef weighs approximately 237g (density: 1000 kg/m³). That serving contains 56.2 g of protein — computed as 237g ÷ 100 × 23.7.

How many grams of Beef do I need to eat to get 30 g of protein? To reach 30 g of protein from Beef, you need approximately 127g — calculated as (30 ÷ 23.7) × 100 = 127g.

Is Beef high in protein? Yes, Beef is high in protein at 23.7 g per 100g. It ranks among the better sources in its category.

What percentage of daily protein does 100g of Beef provide? 100g of Beef provides 23.7 g of protein, which is 47.4% of the reference daily intake (50 g/day for adults, based on a 2000-calorie diet). To reach 100% of your daily protein from Beef alone, you would need ~211g.

What are the most common mistakes when measuring Beef protein? 1. Logging a different prep state than the food actually eaten can change calories and macro density. 2. Sauces, oil, breading, and added ingredients are not included unless they are part of this USDA food description. 3. Assuming every household serving has the same gram weight; use the listed serving anchors when available.

How efficient is Beef as a source of protein per calorie? Beef provides 19.27 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 Beef protein calculator use? The calculator uses protein = weight in grams / 100 x 23.7 g. For example, 100g of Beef gives 23.7 g of protein. Volume entries are first converted to grams using the food density value, then the same per-100g formula is applied.

Is Beef a good food for muscle building or high-protein goals? For muscle building or high-protein goals, Beef is an excellent choice — with 23.7 g of protein per 100g. Beef is also keto-friendly, gluten-free, a high-protein option. For best results, combine Beef with other foods to hit your daily macro targets.

How reliable is the source data for Beef? Beef uses USDA FoodData Central Foundation Foods as the nutrition source, FDC ID 746761. 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.

Why Volume ≠ Weight: Beef Density Explained

Beef 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 Beef.

Data Sources & Methodology

Data source: USDA FoodData Central. Referenced entries: Beef, Round, Top Round Roast, Boneless, Separable Lean Only, Trimmed To 0" Fat, Select, Raw (FDC ID: 746761).

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.
