According to Wikipedia the two variants exist because the digits of large numbers used to be grouped into groups of six digits but in order to improve readability this was eventually changed to groups of three digits and some insisted that with that also the naming should be adjusted. A long scale trillion has three digit groups when using groups of six digits (1,000000,000000,000000) and six after the switch to groups of three (1,000,000,000,000,000,000) which then should be a short scale sextillion but somehow it ended up as a quintillion.
This is the key piece of information for making sense of it. Ultimately the OP's insight is that the number-naming system used in the west is thousands based instead of millions based, but came to that by observing the number-naming outcomes instead of the source notation that led to it.
this is so funny because i always envied english for it being so clear: million, billion, trillion. in german we have these "awkward" names in between: million, milliarden, billionen, billiarden. but now hearing about this long scale it actually does make quite a lot more sense when thinking about it in multiples of millions
Swedish does that as well. miljon, miljard, biljon, biljard.
This is sufficiently confusing to people that every time I see a newspaper article mention something is a biljon of something they have to mention how much it is and remind readers to not confuse it with an American billion (that is only a miljard).
In most contexts when big numbers like those show up though the metric-system comes to the rescue, since things will be referred to as being a mega-something or giga-something etc anyway. That works great until Americans attempt to do it and get the letters wrong or use K instead of k or M instead of m that causes new confusion and then we're back at having to guess what something means depending on what side of the Atlantic it was written.
same in Italian: milione (1E6), miliardo (1E9), bilione (1E12) etc.. the long scale a "one" is 1E6 bigger than the previous one, example: bilione is 1E6 bigger than milione.
Spanish uses the long scale, but lately I've been noticing people mistakenly using the short scale in Spanish more and more, likely due to the influence of English and the internet, sometimes even in news articles and other "professional" publications. You may see someone speaking of "un trillón de dólares" (a trillion dollars), which while it makes sense in English when speaking of federal budgets or the market cap of FAANG, in long scale that's more than the world's entire money supply.
It's especially annoying because it creates ambiguity and renders the *illón-words fairly useless.
If you want to be unambiguously understood, especially in international context, it seems it's better to avoid words beyond "million" altogether.
"million of millions of dollars" or "ten to the twelfth dollars" or "one tera dollar" or even "one EEE twelve" (for programmers) will always be understood correctly, no matter which part of world listeners are from.
In Dutch the word "miljard" for 10^9 is too well known and deeply ingrained to change I think, but with "triljoen" which could either mean 10^18 or a direct conversion from the American English trillion, all bets are off
Yeah, I too think that's likely the direction we're heading, and I'd be fine with either option as long as it was consistently used, this transitional phase is just painful.
In the meanwhile you can say one thousand millions (for what Americans call a billion), like the local tv news does, and for the bigger one say just say millions of millions (what Americans call a trillion), that should be unambiguous enough.
TIL about one more thing US misunderstood and now we have to deal with it. Another one is command key on mac, "borrowed" from road sign indicating "sight seeing place" :)
I don't see how borrowing the Swedish "point of interest" symbol for the command key is "misunderstanding" something - as I understand the story, they just liked the symbol and decided to use it.
Also, I'm certainly not a US apologist, but I also don't see how the US using the short scale is a case of misunderstanding - it sounds like they just decided that it makes more sense that way (and I would agree, although maybe that's just because I'm used to it).
As a kid I stressed our Olivetti divisumma 24 ( https://www.ithistory.org/sites/default/files/hardware/Olive... ) with a million times a million. It entered a perpetual mechanical cycle that even unplugging it could not break. Finally Dad had to attack its innards and tug and twiddle until he pulled out a spring loaded gear and it caught a cog on the next go-round. It lifted its digit arms and printed out a 'partial answer' that was a series of random numbers as wide as the whole mechanism.
He said "please don't do that again." I moved on to torture computers.
And in East Asia, we use a system based on exponents of 10000. I kind of like it, except when I have to think about it and the short/long scales at the same time.
Oh I never got why there was a confusion for the value of billion and co. I always assumed I did not get the proper value, but now it makes much more sense!
On the other hand, I think short-scale millions and billions are used far more often than the larger numbers, and the starts of words tend to be more salient than the ends, so it's useful to have them distinguished by the first letter instead of the last syllable.
(Plus, "milliard, with an 'ard'" doesn't have the same ring to it.)
It is used in all European countries (I don't know any European country that doesn't use it). I know the long scale under the name "European" and the short scale as "American".
>I don't know any European country that doesn't use it
With the exception of people over 70, the UK has pretty uniformly moved to the American system. All of our govt statistics, corporate finances info, day-to-day conversations involving billions refer to "one thousand million"
I'm kinda wondering are there any countries that still use the long scale nowadays? For me the biggest thing I've had to learn is that in Russian we use a short scale, except we don't have "billion" and instead it's "milliard". So it's just that you need to be careful with translating that one word. Are there other countries where the scale "shifts"?
Germany and France do. It can be a PITA when dealing with English texts... But then again when dealing with things in an international context you'll also encounter Chinese and Indian systems for large numbers.
Chinese:
1 yi
10 shi
100 bai
1000 qian
10000 wan
10 x 10000 shi wan (hundred thousand)
100 x 10000 bai wan (one million)
1000 x 10000 qian wan (ten million)
1 x 100.000.000 yì (hundred million)
10 x 100.000.000 shi yi (one billion)
Indian: no idea how it works in practice but it involves crore and lakh...
> Indian: no idea how it works in practice but it involves crore and lakh...
They write thousands just like in the U.S. system, with the same commas: 20,000. But beyond that, the "lakh" is 100k, the "crore" is 10M, and commas in written figures go in twos:
The population of Australia is about 2.8 crores: 2,80,00,000. The Delhi metro area is over 3.4 crores: 3,40,00,000.
They have more unique words for every 100-multiple unit after crore, to go along with the commas, but in everyday practice they don't use those terms. Instead, they go "long" on the crores. Thus, India's population is about 146 crores; the new Mumbai underground Colaba-Bandra-SEEPZ line will cost ₹21,000 crore.
When reporting foreign money, they use the U.S. system with millions and billions as usual: ₹21,000 crore is parenthesized (US$2.5 billion).
But more and more people use "billions" (not billardo, which is our own term for it). The same people that say "diez kas" (for 10k) instead of "diez mil" like they're saving words for doing that (hint: no).
>The same people that say "diez kas" (for 10k) instead of "diez mil" like they're saving words for doing that (hint: no).
I sometimes say (in Portuguese) "dez kapa".
It's just slang. Language changes a lot faster than you realise, and a lot of words that are "normal" to you would illicit the same response before you were born.
Same in Turkey. We say Milliard instead of Billion. In my childhood I can swear it was like Million->Milliard->Trillion->Trilliard. They were in daily language because 1 Million Turkish Lira was like a few dollars. At some point they decided Trilliard does not exist and it became something like a Mandela Effect for me. We never used Billion though.
Yep it's a mess. Most newspapers and official channels just avoid the word billion altogether, just writing "mil milhões" (a thousand million).
AFAIK the exception is the finance world, where I believe B stands for the short scale for a long time, and $1B has been used in newspapers for a long time too due to globalisation of the economy.
>imagine my disappointment when I left home for university, got access to computers and the World Wide Web, and discovered that the names I had learnt were off by several orders of magnitude

It doesn't sound like English, at least in my brain it doesn't register as English, and I may have found a plausible reason: If you look up the amount of English words with the letters "iarda" on them you only find 3 words (at least according to wordmine.info), but French shows 38 words, even just "arda" the difference is huge: 317 vs 2017 words https://www.wordmine.info/french/words-with?minletters=2&max...
The Economist (British) changed from million million -> thousand million in (1944) -
"If it is objected that a billion in this country is reserved for the meaning of a million million, then it can be counter-objected that, if so, it is reserved for a use that interests nobody but astronomers and the historians of German inflation"
The US leading the way in a sensible measuring system.
>This week, for the first time, the note circulation is in excess of £1,000 million. There is, of course, very little real difference between £999 million and £1,001 million—apart from a difficulty for the compositor who works within a narrow column. And yet there is a great psychological barrier, and the setting-down of that extra digit, with its comma following, seems to symbolise the breaking of fresh ground. The totals of revenue and expenditure have, of course, been in ten figures almost ever since the beginning of the war, and the total of the national debt—a rather shadowy notion anyhow—is well into eleven. With the line crossed by a third familiar statistic it is natural to ask what this magnitude of 1,000 million is to be called. There is no word native to these islands. The continental word “milliard” was in some use some years ago, but has not been used very much recently. Well over half the English-speaking peoples, however, use “billion” to mean a thousand million, and if it is objected to this usage that a billion in this country is reserved for the meaning of a million million, then it can be counter-objected that, if so, it is reserved for a use that interests nobody but astronomers and the historians of German inflation. For some time past, The Economist has been using “billion” in American contexts with the American meaning—i.e:, one thousand million. It now seems convenient to extend that usage to British and foreign contexts. Henceforward, in these columns, in the absence of specific indication to the contrary, “billion” means 1 and nine 0’s.
I know we're not supposed to complain about being voted down, but this is a case where the downvoters are simply wrong and need to be corrected.
This is a fantastic educational song designed to teach children how big a billion is by using examples involving hamburgers. I promise it will be the best 80's educational rap you hear all day.
According to Wikipedia the two variants exist because the digits of large numbers used to be grouped into groups of six digits but in order to improve readability this was eventually changed to groups of three digits and some insisted that with that also the naming should be adjusted.

So basically
I'm sorry it had to be done https://www.youtube.com/watch?v=rIB5HEcZBs8
N-illion = 1000^(n-1)
Isn't it more like:
Since the OP was saying groupings use to be by 6-digits, not 3-digits (i.e. "1,000") as seen today.The original long scale makes more sense, billion, bi million, twice six digits.
Yet, mille and milli- mean thousand.
But the suffix -one in Italian is used to indicate something big - spaghetti vs spaghettoni - so a milione is a big thousand, a million.
Thanks!
This is the key piece of information for making sense of it. Ultimately the OP's insight is that the number-naming system used in the west is thousands based instead of millions based, but came to that by observing the number-naming outcomes instead of the source notation that led to it.

I think they forgot "thousandard" = 1,000,000. And million is a thousandard of those.

It's only "mistakenly" until it becomes the norm, which as another Spanish speaking person, I bet that will be the case no long in the future.

I just seamlessly switch scales and units with the language.
When I talk Swedish I think in terms of long scale, 24 h clock, SI units.
When I talk English I think in terms of short scale, 12 h clock, imperial units.
It's like different cultural basis vectors.
Numberphile did a video on this many years ago: https://www.youtube.com/watch?v=C-52AI_ojyQ
Oh I never got why there was a confusion for the value of billion and co. I always assumed I did not get the proper value, but now it makes much more sense!
Long scale seems to be much better because you have to remember fewer prefixes, so with fewer easier to remember rules you get wider coverage
Why didn't this principle win?
On the other hand, I think short-scale millions and billions are used far more often than the larger numbers, and the starts of words tend to be more salient than the ends, so it's useful to have them distinguished by the first letter instead of the last syllable.

I Spanish language we have this dad joke:
¿Que es un millón? Mil miles.
¿Que es un billón? Un millón de millones.
¿Que es un semillón? ???
Una semilla muy grande.
"Mr. President, two Brazilian soldiers were killed yesterday in Iraq." "Oh my god... How many is a Brazilian?"

Same in Ireland, the long scale was already an elderly person thing when I was a child
UK used to do it the European way, but has adopted American way since (IIRC) about 50 years ago. As a Brit I wish we still used the traditional way.
(And despite Brexit, UK still is a European country!)
It may take fifty years, but I think that you will eventually rejoin the EU.
I definitely hope so! (And hope it won't take that long, but it wouldn't surprise me.)
Or whatever the thing is then.

I still don't know which is which. Just give me the power to the 10, Is it 10^9 or 10^12? Who know?
Portugal uses it, but probably due to foreign influence there’s more and more people that use the short scale, which makes everything a mess
Yep it's a mess. Most newspapers and official channels just avoid the word billion altogether, just writing "mil milhões" (a thousand million).

Pretty much all of continental Europe is on long scale. In computing it's masked by SI prefixes. Nobody talks about billion bytes whatever it means.
