  If you take a million one thousand times, how much do you get?-)

  Where "a thousand millions" is not 10^9?

The vagueness of your reply in my attempt to nail down its meaning merely
underscores the barrier to technical communication in international audiences
from the use of either the terms "thousand" or "million".  Americans won't
know what a non-American really means; I'm afraid I'll never know what you
mean...

FYI, my dictionary gives two definitions of "billion" (the American 10^9 and
the British 10^12) but only one definition for "million" (10^6) and one
definition for "thousand" (10^3). So IMHO there can be no ambiguity in
saying thousand million.

This is correct.  10^n is 10^n no matter where you are, it is a (as far as
we know) universal constant.  The problem comes with terminology.  A
"thousand" is the same in US/UK (10^3), so is a "million" (10^6) and,
therefore, so would a "thousand million"  (10^3 x 10^6 = 10^9), but in the
US a "thousand million" is also known as a "billion" but not so in the UK,
it is still a "thousand million" (Or also a "milliard").  The UK reserve the
word "billion" to describe a "million million" (which is known as "trillion"
in the US).  Also, a UK "trillion" is a "million million  million" (quite
the mouthful) or 10^18 ("million"^3, "quadrillion" = "million"^4, etc.). All
in all, it is always better to use scientific notation so as to keep
confusion about such large numbers to a minimum when talking to an
international audience.

What Warp said was "several thousands of millions". While Americans may have
another name for it, one thousand million is still 10^9. There is no other
way it can be interpreted.

Yes, that's right, but I think Greg's original point was that Americans tend
not to use the phrase "thousands of millions" but rather "billions" and
maybe wonder why Warp specified thousands of millions rather than just
saying billions even though they mean the same in American terms.

Well, this is true as long as everyone is working in the same base. 

10^n (base 13) is not the same as 10^n (base 10), so 10^n may not be the
same everywhere. ;-)
