I don't see that is so obvious, you are just used to it.

To me it's obvious that it's 1000*1000^whatever

it's:

1000*1000^-1 one
1000*1000^0 thousand
1000*1000^1 million
1000*1000^2 billion
1000*1000^3 trillion
1000*1000^4 quadrillion

vs:

1000000^0 one
1000000^.5 thousand
1000000^1 million
1000000^2 billion
1000000^3 trillion
1000000^4 quadrillion

Your pattern breaks when it comes to thousand, so I think mine is more 
consistent and logical. Also your numbers grow too fast, and you needed to 
add milliard and billiard to compensate. (I suppose you could say thousand 
milliard and billiard are part of the same x.5 series, but really - two 
interleaving series is an improvement?)

But seriously, different places give things different names, and there is 
no reason to go nuts about it, as long as I know what you are talking 
about, I don't care what you call it.

Read http://en.wikipedia.org/wiki/Names_of_large_numbers and 
http://en.wikipedia.org/wiki/Long_and_short_scales for all the details.

But, back to the subject at hand since we are talking about computers 
here, can't you just use K, M, G?

Oh, and BTW, it's interesting that the SI units grow at the same rate the 
american ones.
