On occasion I like to do fun things like make saffron rice...
But, yeah... if your diet consists of mostly ramen and pbj, ;)

Is this like the thing where they discovered that the police
breathaliser machines were being kept in alcohol to keep them sterile?

Gold's density is around 19.2 g/cm^3, and so a troy ounce of gold is
about 1.6 cm^3, which is about the volume of four and a half American
pennies. Not a bad way to carry around a few hundred dollars in value.
Just don't lose it.

John

That doesn't sound quite right. Here's an ounce of gold and an American
quarter. It's just over 3 cm in diameter and about 3mm thick.

A quarter is not as voluminous as 4.5 American pennies.
In any event, a Troy ounce is about 31.104 grams, and gold is 19.3 grams
per cm^3 (I misremembered it as 19.2 when making my earlier
calculation), giving a volume of 1.611 cm^3 for a Troy ounce of gold.
A coin, 3cm in diameter by 3mm thick, will be about 2.1cm^3. What's the
alloy content of the coin?
Regards,
John

...so a 1.1 x 1.1 x 1.1 mm block of this stuff costs £664, eh? That's
pretty freakin' expensive, right there!
I'd hate to imagine how much a solid gold ring costs.

The one I posted a picture of? It's a bullion coin, so 24k or better.
