World Gold Reserves, Swimming Pools and Pubs

My German colleague, Ulrich Heker, has lately been lamenting the increasing cost of gold for dental technicians. Well, the solution might be closer to home. Germany has the second largest stock of gold in the world, as co-director Jane found out in a fit of lateral research.

 America leads (of course!) with an amazing 8133 tonnes of the soft precious metal. Germany follows with 3390. We Brits have a paltry 310 tonnes of the stuff – presumably mainly in bling. What surprised me was that the influencal lender to nations, the International Monetary Fund “only” has 2814 tonnes.

Apparently the total known world gold reserves amount to 31,320 tonnes, which seems a surprisingly small amount.

Gold is indeed a precious metal.It is not only beloved of for its decorative glint. The high conductivity and chemically inert metal is also used for electrical contacts and circuit boards.

Gold is also very dense, at 19.3g per cubic centimetre it is 19.3 times heavier than water. To put it in context, if a large 2 litre milk bottle on a supermarket shelf was instead filled with gold, it would weigh as much as a 12 year old (38kg) .

So taking its high density into account, what would 31,320 tonnes of gold look like if collected in one place? Well, the total volume would be 1623 cubic metres. Now that is equivalent to a solid cube of less than 12m x 12m x 12m.

Typically, this is expressed as fitting into ONE olympic sized swimming pool. But I needed something I could relate to locally. Was there a suitable building with the same volume?

Yes! The Waggon and Horses pub looked large enough. I phoned publicans David and Louise to check. David and I worked out that there was cellar space and of course, soon there would be the restaurant extension at the rear.

So all the whole world's gold reserves could fit into the same space as the Waggon & Horses in Milton!

David's last comment was “When it arrives, just give me a pound of the stuff and I'll happily move out into the shed!”
