Metric and Imperial tanks.

Very, very well put. And this from an objective Canadian!

The inch came from a thumb?? How did they figure that? I have small hands, and every part of my thumb is quite a bit more than an inch. On me, an inch is precisely the distance between the tip of my index finger and the first knuckle.

People were much smaller back then!!!!

An inch was originally the width of a man's thumb. Of course, since the Villiage Blacksmith always felt cheated when he bought a 6" roll of twine, it was later officially defined as the length of "3 barleycorns, dry and round, placed end to end lengthwise".

Nice to know that Imperial measurements are based on such scientific constants!

Oh, the width of a thumb... that's better...

Man... Why does it take a Canadian to tell us all this?

I think I´d have a better chance of understanding that if it was in german or french or whatever your native language is...

Not all 12 liter tanks are 300bar, most are 200 or 232...I actually don´t think I´ve ever seen one that is 300bars...the biggest 300bar tank I´ve seen was a 10l...

German, apparently, according to her .de web page.

Good luck understanding that, either.

Still I'm glad she's here.
