Beef Calories — Frequently Asked Questions
How much calories is in 100g of Beef? 100g of Beef contains 141 kcal of calories (USDA FoodData Central).
How much calories is in 1 cup of Beef? One US cup of beef weighs approximately 237g (density: 1000 kg/m³). That serving contains 334.2 kcal of calories — computed as 237g ÷ 100 × 141.
How many grams of Beef do I need to eat to get 500 kcal of calories? To reach 500 kcal of calories from Beef, you need approximately 355g — calculated as (500 ÷ 141) × 100 = 355g.
Is Beef high in calories? Beef is low in calories at 141 kcal per 100g. If you're targeting this nutrient, Beef alone is unlikely to be sufficient.
What are the most common mistakes when measuring Beef calories? 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 calories per calorie? Beef 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 Beef calories calculator use? The calculator uses calories = weight in grams / 100 x 141 kcal. For example, 100g of Beef gives 141 kcal of calories. 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 weight gain or calorie surplus goals? For weight gain or calorie surplus goals, Beef is a modest contributor — with 141 kcal of calories 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 2646173. 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.
Should I measure Beef raw or cooked? Beef should be logged in the same prep state as the source record. If you weighed it cooked, avoid comparing it directly with a raw entry unless a cooked yield factor is available.
How to Calculate Beef Calories
- Weigh raw. Place your beef 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 calories content for your exact portion.
- Compare servings. Use the serving range table below to quickly compare calories 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: 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, Boneless, Choice, Raw (FDC ID: 2646173).
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.
