Have you also wondered the age old question, how many cans equal to a pound? Well I have the answer for you. The number of cans it takes to make a pound are determined by several different factors. First, if the can is empty or full; second, if the can is crushed. Last, how large the can is. Okay, all those factors moved to the side. On average, it takes about 32 crushed 12 oz soda cans to equal one pound.
