Thousands, millions, billions...\nAt least more then, let's see: me, you and those 6 answerers, so that makes... 8

The population of the earth is 6.25 billion. The population of the U.S. is in excess of 300,000,000. Mud people, quit breeding.

Twenty billion is still 22.2 times bigger than 900 million, no matter how it is written.\n\n20 billion is 2.0 x 10^10, while 900 million is 9.0 x 10^8.

Have a look at http://en.wikipedia.org/wiki/Long_and_short_scales - this explains the origin of the billion with 12 or 9 zero's.  In fact now in Britain it's widely accepted that a billion is a thousand million, so calling a billion with 12 zero's a British billion is now misleading.

It depends where you are\nIn UK\n1 billion is 1 million millions and 1 trillion is 1 billion billions\n\nIn USA\n1 billion is 1 thousand millions and 1 trillion is 1 thousand billions\n\nStrictly speaking, the American billion is actually a milliard.\n\nThe answer given by the person below from wikipedia is only half the answer and if you go to wikipedia you will get the full answer which is as above.

You have a billion numbers from 000,000,000 to 999,999,999.  These are all the possible combinations of digits 0 to 9 at each position (units, tens, hundreds, thousands, tens of thousands etc... to hundreds of millions).\n\nYou have 100,000,000 numbers starting with a 0.\n100,000,000 starting with a 1.\netc...\n100,000,000 starting with a 9.\n\nSince 0+1+2+3+4+5+6+7+8+9=45, this means the sum of all first digits is 45 x 100,000,000 = 4,500,000,000.\n\nSimilarly you will find that the sum of alll second digits (tens of millions) is also 4.5 billion.  Same for third digits, etc... and for ninth digits(units).\n\nSo the sum of all digits from 0 to 999,999,999 is 9 times 45 billion = 40,500,000,000.\n\nYou need to add 1 for the number 1,000,000,000, so the answer is 40.5 billion + 1 = 40,500,000,001.

As one needs larger and larger numbers in science, one resorts to scientific notation (or sometimes engineering notation, which is similar)\n\n1 million = 10^6\n1 billion = 10^9 (also known as 1 milliard in the UK)\n1 trillion = 10^12 (also known as 1 billion in the UK)\n\nbut as one starts to get fatigued from \n\nquadrillion, quintillion, sextillion, septillion, octillion, etc, then it just starts to become easier to use the scientific notation. \n\n10^6 means a 1 with 6 zeros after\n10^9 means a 1 with 9 zeros after\n10^12 means a 1 with 12 zeros after\n\nA google is a really big number \n\n1 google = 10^100, or a 1 with 100 zeros after\n\nThis is much bigger than the estimated number of particles in the whole universe, 10^70 (the so-called Eddington number)\n\nAn even bigger number is the googleplex, which is a 1 with a google of zeros after it. Obviously, this would be a very hard number to write down. \n\nIf you want to play around with really really big numbers, like infinity, then you can consider the transfinite numbers. \n\nIt turns out that there are different types of infinities. \nThe smallest one is aleph knot (a Hebrew symbol with a zero subscript), that is the same as the number of integers that exist. There are "bigger" and "bigger" infinities after that. I included a link that you can look at to get you started.
