imperial/metric poll

[NickFitz]

There are useful things about metric, like the fact that 1 litre of water weighs 1 kilogramme. And, coincidentally, one kilogramme of water has a volume of one litre.

I don't get why car performance is still measured in miles per gallon when a lot of people (i.e. me) have probably got no idea what a gallon looks like, weighs or costs.

One Imperial (i.e. British, not American) gallon of water weighs 10lb.

Easy way to remember it: "A pint of water weighs a pound-and-a-quarter".

HTH.

"A pint of pure water weighs a pound-and-a-quarter"

At a standard latitude?

At a standard latitude?

At what temperature?

[TimberWolf]

At what temperature?

Ah, I was just Wikiing and apparently the pound is a unit of mass like the kilogram, not a weight, so weighs the same at any latitude. In commerce weight and mass are synonymous (apparently) so I imagine a pound weighs the same at any latitude too. Dunno what unit there is for a force in Imperial, or commerce, pounds-force or something I expect. Eeek.

So there we have it...

It's the volume of 10 lbs of water at 62 deg F. (16.66 deg C).

It's the volume of 10 lbs of pure water at 62 deg F. (16.66 deg C).

And the metric system was invented by an Englishman.

Also a cracking good cryptanalyst. I've read his book, it is rather good. YMMV

Are you going to update wiki?

Did you know that the speed of light in furlongs per fortnight is exactly one trillion?

That'll be a Merkin trillion, I presume.

[BrilloPad]

Did you know that the speed of light in furlongs per fortnight is exactly one trillion?

the speed of light in vacuum is approximately 1.803×1012 furlongs per fortnight, or rather 1.803 terafurlongs per fortnight;
