How to weigh canned tuna in water
Use the edible tuna portion and check whether the can's panel refers to drained fish or the product with liquid. A net can weight can include water. Tuna in oil, tuna steak and mayonnaise-based tuna salad need different entries.
Calculate your own canned tuna in water portion
For the 120 g example, multiply the source amounts by 120 ÷ 100 = 1.2. The unrounded energy calculation is 99.1 × 1.2 = 118.92 kcal, displayed as approximately 119 kcal. Use the same factor for protein, available carbohydrate, fat and fiber.
For another amount, replace 120 with your own edible weight. Keep the preparation as canned tuna in water reference; if your food is prepared differently, choose a matching reference or calculate its recipe instead.
How preparation changes the estimate
For a tuna sandwich, count bread, mayonnaise, vegetables and the fish. The table does not identify tuna species or quantify mercury. Pregnancy and other groups with specific fish advice should follow their local official guidance on species and frequency.
