What weighs more: a pound of steel, or a pound of feathers?
What's a "pound of steel"? I'm pretty sure I would need to know how you measured that.
What is a "pound of feathers"? There isn't any way to specify that it's feathers that is a "pound," at least not in the same way as "a pound of sugar" is a single thing. If you are talking about a bunch of feathers which was weighed, that would be a pound.
(I'm sure you've already made some joke about "a pound of steel" and how that would be just feathers, but if you haven't, see if you can come up with something on your own.)
