One hundred grams of meat, including beef, pork, poultry or seafood, is equal to 3.5274 ounces or 0.22046 pounds. The physical size of a 100-gram portion of whole meat, such as a steak or chicken breast, is comparable to a deck of playing cards.
When it comes to shredded or cubed meat, a 100-gram portion is equal to a little less than 1/2 cup. For seafood, such as shrimp or scallops, a 100-gram serving is equal to approximately five shrimp or six to seven medium-sized scallops. For convenience, some recipes and diet plans round the grams-to-ounces conversion up to 4 ounces.
