Real-World Salmon Serving Sizes
- 1 salmon fillet (medium) (~170g): 33.7 g protein. A standard salmon fillet from a grocery store weighs approximately 170g raw.
- 3 oz serving (~85g): 16.8 g protein. The FDA standard serving size for fish is 85g (3 oz), equivalent to roughly a deck of cards.
Common Salmon Measurement Mistakes
- Counting farmed Atlantic salmon as the same as wild-caught: wild salmon has slightly fewer calories and less fat.
- Forgetting that salmon shrinks ~25% when cooked, concentrating its protein to ~26g/100g cooked.

How to Calculate Salmon Protein
- Weigh raw. Place your salmon 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: Salmon Density Explained
Salmon is dense (~1050 kg/m³ ≈ water). A 1-cup measure holds approximately 248 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 Salmon.

Data Sources & Methodology
Data source: USDA FoodData Central. Referenced entries: Salmon, Atlantic, raw (FDC ID: 175167).
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.
