What weighs more, a pound of feathers or a pound of gold?

I recently talked to a geeky friend and they asked me the question. He said it was a weird answer.

I thought they were the same, and he said I was wrong.

    Gold is measured in troy pounds, which consist of 12 troy ounces of 31.10 g each, or about 373 g per troy pound. Feathers are measured in avoirdupois pounds consisting of 16 avoirdupois ounces of 28.35 g each, or about 454 g.

    So a pound of feathers weighs more than a pound of gold.

    Somehow the answer is not totally certain.

    For example, a pound of feather on top of Mt Everest

    and a pound of gold below sea level.

    Yep, a pound of feathers weighs more, because pound has a different meaning. It's amazing how many wrong answer you got. It's an old, old, trick question.

    They weigh the same if it is a pound of the substance, but they will take up different volumes!
