The title may sound silly, but the question is serious:
When I buy butter, the package says Net Wt. 16oz, and I trust this because the authorities regulate such things.
Inside the package, each stick is divided evenly into 8 tablespoons. Now, although a fluid ounce of water might weigh almost exactly a 1/16 of a lb., butter is like 80% fats. There's no way a fluid ounce of butter (exactly 2 tablespoons) weighs 1/16 of a lb.
So, how many tablespoons of butter are there in a "tablespoon" (per the package marking) of butter?
