Sure, you can look up all that information in the PETAfile. Just don't get caught.

Check that. Things change.

Wikipedia: Long and short scales

Quote:
The existence of the different scales means that care must be taken when comparing large numbers between languages or countries, or when using old documents in countries where the dominant scale has changed over time. For example, British English documents from 1900 used long scale values, which are different from current British short scale usage. Both scales were used in France and Italy at various times in their history, but these countries (and most other European countries) now officially use long scale. For example, the French word billion, the German word Billion and the Dutch word biljoen all refer to 1012. This translates to the short-scale term "trillion" (1012), not "billion" (109 in the short scale). See Current usage below.
The Systeme International prefixes (Wikipedia) mean what they mean and aren't part of this short/long scale nonsense.

How often does that screw up papers presented overseas?

Standard to 'merkin you mean

Nyah, nyah, our trillion is a million times larger than your trillion.
It's funny how, in a country that seems awfully facinated about everything big, your numbers are smaller than ours.

The American naming seems to follow a logical pattern. 1000 times one thousand = one million, one thousand times a million is a billion, 1000 times a billion is a trillion, 1000 times a trillion is a quadrilion = 10E15.
Are you saying a million times a million is called a billion in Austraila? A billion times a billion 10E24 is called a trillion in Austraila? A trillion times a trillion is called a quadrillion = 10E48 in Austraila? That is also a logical pattern. Neil

American scheme: XXillion = 103*(XX+1)
European scheme: XXillion = 106*XX = millionXX

European scheme, Danish supplemental:
XXillion = 106*XX
XXilliard = 106*XX+3 = XXillion*1000

Where XX is a contracted form of the number in bastardized latin.

The american scheme is consistent but not really logical.
Calling it a billion because you started with a thousand and then multipled that with a thousand two times seems like an off-by-one error to me.

Swedish also uses the -illion, illiard scheme (well, we spell it -iljon, -iljard), and the American convention annoys me no end.

The reasonable solution, of course, is using exponential notation or SI prefixes.

http://en.wikipedia.org/wiki/Names_of_large_numbers

also from wiki-

Quote:
Milliard is a French-derived word meaning the number 1,000,000,000 (109; one thousand million; SI prefix giga). It is not used in American English and is rare in other forms of English - the preferred term being 'thousand million'. When South Africa adopted the metric system in 1971, "milliard" was recommended by the Metrication Board, but has often been ignored in practice. During the 20th century, the short scale "billion" superseded 'thousand million' to become the normal term in the most of the English-speaking world.

"Milliard", or a version thereof, is common to many languages other than English.

That doesn't sound right.

Thinking as I type, I get:
Our trillion = 1000 times our Billion = 1E12
Your trillion (if I understand it right) = Your Billion times your Billion = 1E12 * 1E12 = 1E24.

So your Trillion is our trillion squared. A trillion times as big, by our scale. A billion times by yours.

Seems like the long scale trillion ceases to be a very useful number, even for national budgets.

I probably got something wrong, but on this board I rest assured of being corrected if I did!

You don't understand right. A long-scale trillion is (million)3, that is 1018, so "only" a million times larger than the short-scale one.

I don't understand why they mention the metric system. There is no connection between the adoption of metric units and the definition of billion, as far as I know.

- Anglo-Saxon billion = second group of three decimals after the thousand. In other words 1,000 is a thousand, therefore 1,000,000,000 is a billion. Has 2 x 3 + 3 = 9 decimals.

- Continental billion = a million squared (1,000,000 x 1,000,000 = 1,000,000,000,000); has 2 x 6 = 12 decimals.

They were just saying that it was the metrication board who proposed the name. I has nothing to do with metrics.

Thanks. But now it's no more logical than the 'Murican way. Just incrementing by 1E6 each time instead of 1E3.

Except we start by counting the second million as two, you start by counting the third thousand as two.
