Question

butchers use to measure the weight of a meat​

Answer 1

Weigh the meat when it's uncooked, or look at the total amount contained in the package. ... For example: Let's say the package of raw meat you are about to cook weighs 1 lb. If you want to make two, 8 oz. portions, knowing that this package weights 16 oz., you can cook it, weigh it after, then just divide that by two.
