Why do canned goods come in such an obscure number like 14.5 ounces instead just a solid 16oz (1lb.)

Question

Might just be me, but imo I find it weird that canned goods come in 14.5 ounces instead of an even 16 ounces. Since that would just be a well rounded number and would be 1lb it just seems more rounded to me.

Answer 1

Canned goods are a fixed volume of food. Different foods have different densities. So given the same volume, different foods will have a different mass in the same can.
