There are usually numbers that describe the size of shrimp. These numbers tell you approximately how many shrimp are in one pound. The larger the shrimp, the fewer it takes to make a pound. Ask the seller where you plan to buy the shrimp what the "count" of the shrimp is for the size you want. They can tell you how many shrimp will be in one pound. The largest shrimp I've purchased were (10-16) size. That meant there were from 10 to 16 shrimp in one pound. If you buy that type of shrimp, you'd need about 4 or 5 pounds to be sure you had 48 shrimp.
