With the recent talk about the economy, we are certainly getting used to the word trillion. But, what comes after trillion. Here is a list of the BIG numbers we use in English. I got this information from Yahoo answers! If you make it to Googol, you can be proud! Pronunciation here is certainly tough and perhaps I can make an audio file for the correct pronunciation. The internet search giant Google is named after the Googol!

Billion has 9 zeros
Trillion has 12 zeros
Quadrillion has 15 zeros
Quintillion has 18 zeros
Sextillion has 21 zeros
Septillion has 24 zeros
Octillion has 27 zeros
Nonillion has 30 zeros
Decillion has 33 zeros
Undecillion has 36 zeros
Duodecillion has 39 zeros
Tredecillion has 42 zeros
Quattuordecillion has 45 zeros
Quindecillion has 48 zeros
Sexdecillion has 51 zeros
Septendecillion has 54 zeros
Octodecillion has 57 zeros
Novemdecillion has 60 zeros
Vigintillion has 63 zeros
Googol has 100 zeros.
Centillion has 303 zeros (except in Britain, where it has 600 zeros)
Googolplex has a googol of zeros

If you want some more advanced reading about science and really really big numbers try these. Don’t worry if you can’t understand. This is really advanced!
