Welcome to the Tilapia Iron Calculator — a practical tool for anyone tracking their daily iron intake. Tilapia is a popular, lean white fish, but its iron content is often misunderstood. This calculator helps you estimate the milligrams of iron in your serving of tilapia, whether you're cooking from raw fillets, using cooked portions, or following a recipe that lists ounces or grams.
Simply enter your serving size, choose the unit (grams, ounces, or fillets), and select the preparation state (raw or cooked). The calculator uses standard USDA nutrition data to give you an accurate iron estimate, along with a breakdown of how it fits into your daily iron needs. Perfect for dietitians, fitness enthusiasts, and anyone managing anemia or iron deficiency.
Use the quick-fill buttons for common serving sizes, and explore the detailed results to see your iron contribution as a percentage of the Daily Value. Start calculating now and take the guesswork out of your nutrition tracking!

How to Use This Tool
Using the Tilapia Iron Calculator is straightforward. Start by entering your serving size in the input field. You can specify the amount in grams, ounces, or whole fillets — the calculator will convert everything to grams for you. Next, choose whether your tilapia is raw or cooked (dry heat). This matters because cooking affects the iron concentration per gram due to moisture loss. Then click "Calculate Iron" to see your estimated iron content in milligrams, along with the percentage of the Daily Value (DV) it provides.
For quick reference, use the preset buttons for common serving sizes like 100 g, 150 g, or 4 oz. These are handy when you're following a recipe or a meal plan that specifies a typical portion. The reset button clears all inputs and results, so you can start a new calculation instantly.
How It Works
The calculator uses standard USDA nutrient data for tilapia. According to the USDA FoodData Central, raw tilapia contains approximately 0.56 mg of iron per 100 grams, while cooked tilapia (dry heat) contains about 0.24 mg per 100 grams. The difference is due to water loss during cooking, which concentrates other nutrients but also changes the per-gram values.
The calculation is simple: first, convert your serving size to grams. If you entered ounces, multiply by 28.3495. If you entered fillets, we assume an average raw fillet weight of 150 grams (a typical portion). Then, multiply the grams by the iron density (mg per 100g) and divide by 100. Finally, to show the Daily Value percentage, we divide the iron amount by the recommended daily intake of 18 mg for adults and multiply by 100.
Note: The Daily Value of 18 mg is based on a standard 2,000-calorie diet. Individual needs may vary, especially for pregnant women, athletes, or people with iron deficiency.
Worked Examples
Example 1: You eat a 150 g raw tilapia fillet. Iron = (150 / 100) × 0.56 = 0.84 mg. That's about 4.7% of your daily iron needs.
Example 2: You have a 6 oz cooked tilapia portion. First, convert to grams: 6 × 28.3495 = 170.1 g. Iron = (170.1 / 100) × 0.24 = 0.41 mg. That's about 2.3% of the DV.
Example 3: A recipe calls for 200 g of raw tilapia. Iron = (200 / 100) × 0.56 = 1.12 mg, which is 6.2% of the DV.
Tips & Best Practices
- Weigh your tilapia before cooking if you're tracking raw values, and after cooking if you're tracking cooked values. The calculator handles both, but be consistent.
- If you're using frozen tilapia, thaw it completely and pat it dry before weighing to get the most accurate measurement.
- Remember that iron from fish is heme iron, which is more easily absorbed by the body than non-heme iron from plants. Pairing tilapia with vitamin C-rich foods (like lemon juice or bell peppers) can further enhance absorption.
- For a complete nutrition profile, consider tracking other micronutrients like zinc and vitamin B12, which are also found in tilapia.
Factors Affecting Accuracy
The iron content can vary slightly depending on the fish's diet, farming conditions, and cooking method. The USDA values are averages from many samples, so your actual fillet may differ by a small margin. Also, if you cook tilapia with other ingredients (e.g., in a sauce), the iron content of the whole dish will include contributions from those ingredients. This calculator focuses solely on the tilapia itself.
For the most precise results, use a kitchen scale and refer to the nutrition label on your specific product if available. The USDA FoodData Central is an excellent resource for detailed nutrient information.
Frequently Asked Questions
Is tilapia a good source of iron? Tilapia is not particularly high in iron compared to red meat or legumes. A typical serving provides only about 2-6% of the Daily Value. However, it's a lean protein that can contribute to your overall iron intake, especially when combined with other iron-rich foods.
Why does cooked tilapia have less iron per 100g? Cooking causes water loss, which concentrates nutrients, but the iron content per 100g actually appears lower because the weight of the cooked fish is less than the raw weight for the same amount of fish. The total iron in the fillet remains roughly the same, but the per-gram value changes.
Can I use this calculator for other fish? No, this calculator is specifically calibrated for tilapia. Other fish like salmon or tuna have different iron contents. For those, you'd need a separate calculator or reference table.
Where can I find more detailed nutrition data? The USDA FoodData Central is the authoritative source. You can search for "tilapia" and find complete nutrient profiles for raw and cooked forms.
