Here's one for you guys: What weighs more, a ounce of feathers or an ounce of gold? How about a pound of feathers vs a pound of gold?.
The answers: Ounce of gold weighs more, but a pound of gold weighs less.
Why?: Gold is measured in troy ounces which is heavier than a normal ounce. But a troy pound is only 12 ounces. Now you know.
