> In the U.S., an ounce of flour weighs less than an ounce of gold.
Wait, what?
I mean: WHAT?!
There's a children's riddle here: "what weighs more: a pound of feathers or a pound of lead."
I hesitate to ask what the US answer to this would be.
It's the avoirdupois ounce (exactly 28.349523125 g) for everything but precious metals, where the Troy ounce is used (exactly 31.1034768 g).
Two different units, both called an ounce.
