When a recipe calls for a 16 oz block of cheese to be shredded, it typically translates to about 4 cups of shredded cheese.

This conversion is based on the general rule that 1 cup of shredded cheese weighs around 4 ounces. Therefore, a 16 oz block of cheese, when shredded, would yield approximately 4 cups of shredded cheese[3][4].
