This deliberately narrow calculator does not pretend that beef, lamb, pork, poultry skin and processed meats share one value. Select the exact cut, visible fat, skin and raw/cooked state in USDA FoodData Central or use your product label. The default is cooked edible weight without bones or skin.

Raw and cooked weights are different

Roasting changes moisture and may discard fat. A raw 150 g portion cannot automatically use the cooked density for 150 g. For batch cooking, combine a matching starting ingredient reference with actual cooked yield. Sauces, breading and retained oil are additional ingredients.
