But that's not what "less nuts" means. The same mass of nuts... Will be the same mass. That's how mass works, unless like the previous commenter mentioned the nuts are truly less dense. I was also confused by the phrasing the OP used
As far as I'm aware, half gallon isn't 58 ounces so that's not what that container is. You can't just say that there is a new conversion factor
Like the half gallon jugs that are now 58 ounces or whatever.
