Ok This is what I found and if I remember correctly as I was taught
Million, Billion, Trillion...

© Copyright 1999, Jim Loy

People sometimes ask me the names of the large numbers. Here is a table. The system used in the U.S. is not as logical as that used in other countries (like Great Britain, France, and Germany). In these other countries, a billion (bi meaning two) has twice as many zeros as a million, and a trillion (tri meaning three) has three times as many zeros as a million, etc. But the scientific community seems to use the American system.

Number of zeros-U.S. & scientific community-Other countries
3-thousand-thousand
6-million-million
9-billion-1000 million (1 milliard)
12-trillion-billion
15-quadrillion-1000 billion
18-quintillion-trillion
21-sextillion-1000 trillion
24-septillion-quadrillion
27-octillion-1000 quadrillion
30-nonillion-quintillion
33-decillion-1000 quintillion
36-undecillion-sextillion
39-duodecillion-1000 sextillion
42-tredecillion-septillion
45-quattuordecillion-1000 septillion
48-quindecillion-octillion
51-sexdecillion-1000 octillion
54-septendecillion-nonillion
57-octodecillion-1000 nonillion
60-novemdecillion-decillion
63-vigintillion-1000 decillion
66 - 120--undecillion - vigintillion
303-centillion
600--centillion

So everything clear as mud now?
