Remember Africa is about three times larger than Canada

It's a map of the largest PDF, world for scale

There is truth in meming

American style petty bullshit isn't going to accomplish anything. This kind of thing costs Canadians and doesn't impact the US at all. This is the exact kind of petty bullshit Trump does regularly since it's popular with Americans.

British Columbia basically did a similar thing by declaring permanent daylight savings time because, according to the premier, they're no longer going to wait for the US to move as well before moving themselves.

Except now the situation is objectively worse than it was before, because BC is geographically in the UTC-8 zone, but permanent Pacific Daylight Time is the same as permanent Mountain Standard Time (UTC-7). Except they don't call it Mountain Standard Time in BC, they stubbornly continue to insist they're in the UTC-8 zone. Except they don't call it "Pacific Daylight Time" either, they call it just "Pacific Time". No "Daylight". Despite the fact that their standard time is what the rest of North America calls Mountain Time.

They had four good choices, and chose none of them:

• UTC-8 year round, call it "Pacific Standard Time"
• UTC-7 year round, call it "Mountain Standard Time"
• UTC-8 or UTC-7 year round, call it "Western Canada Time".

Decent idea, rubbish execution.

Why is legal?

Really? I'll need to pay closer attention next time I go to Target or Office Depot...

Letter A4? Lol. Hopefully businesses start advertising things by the double-pounder-kg or the quart-Litre haha

Is letter A4 just A4 with emotional support?

Same, I figured 8 1/2 x 11 was yet another example of our uniquely pig-headed obstinance.

A4 folded is A5

What on earth are you on about with those numbers? 😅

A0 is the base size, with an area of one square meter. Fold that in half and you get A1. Fold that in half and you get A2, and so on. Regular printer paper is A4. You’ll rarely, if ever, see sizes smaller than A6.

They do have a paper that can fold once to get a US letter though; i am only posting about it because i only learned about it two years ago: 11x17, aka, "tabloid" size.

Some desktop printers can even print on it.

And IIRC A0 is 1 m².

Beautiful.

And that's how you choose a system over another,because it makes things easier

does all this A paper standerd business have to do with the fact that you can't fold any paper in half more than 8 times?

american sizes do the same thing, just only five steps in ANSI sizes, and not really that well known outside of the industries that use the paper sizes, such as printing shops.

smallest being u.s. letter (A4 equivalent) is "ANSI A", 8.5x11in...

largest being the full sheet (A0 equivalent) is "ANSI E", 34x44in...

with the expected three steps between for B, C, and D.

going smaller than u.s. letter and ANSI A.. letter halved (4.25x5.5in) 'half letter' is a common notepad and post card size; and halved again (2.12x2.75in) is a common label size.

There is 11"×17", it's called Ledger paper.

This doesn't make the american system okay.

The aspect ratio of the A series of paper is √2, so every doubling or halving of the size retains the same aspect ratio. If you want to save paper and print at half size, you can just do that and it works flawlessly. However doing it this way means very unmemorable decimal unit dimensions.

Half letter and tabloid are much taller than letter so you have to either have overly large margins on the top and bottom, or you have to reformat your document if you ever want to change the sizes.

Though specialty paper suppliers do sell 22x17 paper if you really want to double fold to get letter paper. 11x17 is twice the width of letter which works for printing bifold books in letter size. Its just the scaling aspect ratio thing. Sizes in multiples for bookmaking do exist in both systems.

What's the next step up after A0?

I'll always upvote Matt Parker

It really doesn't matter in practice. Important part is that you can fold A4 into A5

Solution: use bigger pieces of paper. EZ

I wonder what it would take to make paper with more precise measurements, say to the nearest 100 micrometres.

I do not have time to get into the video so i'm sorry if this is mentioned, but do printers have an error margin to deal with this?

Ho ho, let's not overreact

How would that even work? Do you expect the passenger to operate a shotgun with their left hand/eye? Just shove their entire body out the window?

Why would that upset New Englanders only? Pretty sure this would upset every American, not just the Yanks.
