How efficient is Egg white as a source of calories per calorie? Egg white 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 Egg white calories calculator use? The calculator uses calories = weight in grams / 100 x 52 kcal. For example, 100g of Egg white gives 52 kcal of calories. Volume entries are first converted to grams using the food density value, then the same per-100g formula is applied.
Is Egg white a good food for weight gain or calorie surplus goals? For weight gain or calorie surplus goals, Egg white is a modest contributor — with 52 kcal of calories per 100g. For best results, combine Egg white with other foods to hit your daily macro targets.
How reliable is the source data for Egg white? Egg white uses USDA FoodData Central reference as the nutrition source. 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 Egg white raw or cooked? Egg white 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 Egg white Calories

- 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: Egg white Density Explained
Egg white is dense (~1030 kg/m³ ≈ water). A 1-cup measure holds approximately 244 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 Egg white.

Data Sources & Methodology
Data source: USDA FoodData Central.
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.
