A0 paper is just under 3’ x just under 4’. It would not surprise me if that fit on a 3’x4’ printing press.

I always remember people multiplying the price per litre by 4 to get the approximate price per gallon... I wonder if people still do?
As for coinage, my dad, grandparents, uncles would always call a 5p piece a shilling, and 50p was 10 bob right into the 80s... i didn't know what they were on about
They would have a fit if they found out Freddy chocolate cost 7s & 6d today :-)

i was thinking that too... but it would be awkward. A0 would be a square, A1 would be a long oblong, A2 would be square, A3 a long oblong, A4 a square... and so on.

Because 1000mm x 1000mm is a square.
If you did that then even numbered paper sizes would be 1:1 and odd would be 1:2. It would be a useless paper sizing system.

Because the wanted to keep the traditional shape.
And cutting a square in half doesn't result in two pieces of the same shape, while cutting any Ax size in half across the longtitudinal axis results in two pieces which are the same shape as the original, but half the size,.

BA (British Association) threads - 2BA isn't uncommon on older bikes - are also metric, although only 0BA really gives it away.
Before you run an M5 tap through the tight mudguard eyes on that 1960s frame, try a 2BA bolt.

When I was a nerdy teenager I worked in an old fashioned hardware/ironmongers. One of my jobs was sorting a chaotic mess of loose nuts and bolts. Metric, whitworth, BA machine screws, BSF and BSP, different kinds of heads. I loved it as it meant it kept me away from the idiot customers.
A year or so later I was in the shop and my lovely labelled bins were all in a right mess.

Being a Yank, I did not know that road signs in the UK were not metric. Of course I use miles these days, but it's American miles, which are something like .9 Imperial miles. I once used metric for my cyclocomputer, made me feel really fast until I did the math.
PSI for tyre pressure. Fahrenheit for temperature, celsius just doesn't have enough numbers to describe the horrid weather in the USA.

American miles and UK miles are the same in normal usage. They are both 1,760 yards (1609.34 metres).
The US did also use to have a "survey mile" which was the same number of feet, but used a fractionally different size of foot!. But even that was only 3 mm different in length (and longer, not shorter).

And it also wouldn't have been each size being half of the one above - those are all a quarter of the size (in terms of area) of the one above.

Have they heard of folding the letter before putting in an envelope?

Folding the letter and applying sealing wax, surely?

Ah, US paper sizes.

It's US gallons that are smaller, because you have 32 fl oz in a quart and we have 40. Not that we use quarts much: we use pints (half a quart) and gallons (8 pints/4 quarts).
