How much does a scallop weight?

The weight of a scallop can vary significantly depending on the species and size. Typically, a single sea scallop weighs between 1 to 2 ounces (28 to 56 grams), while smaller bay scallops weigh about 0.5 to 1 ounce (14 to 28 grams) each. When sold in shells, the total weight will include both the scallop and the shell.
