The number of cans of crab it takes to equal a pound can range anywhere from one can to four cans. It depends on the company and the can size.
For instance, Bumblebee sells canned crab in 6-ounce cans, which is the net weight. The drained weight is 4.25 ounces, so it takes a little less than four cans to equal a pound, which is 16 ounces. On the other hand, Philips sells 1-pound cans, so only one can would be needed. To figure out how many cans are needed for a recipe, the consumer should check the size of cans available for purchase.
