You see, there's a lot of disagreement on how to name big numbers. There are basically two systems, the English system and the American system. Here's a chart that lists equal numbers in each row: English: American: Number: Thousand Thousand 10^3 Million Million 10^6 Thousand Million Billion 10^9 Billion Trillion 10^12 Thousand Billion Quadrillion 10^15 Trillion Quintillion 10^18 So those are pretty different systems! In the English system, the name reflects the powers of 1,000,000, so your number, which is a thousand times 18 powers of 1,000,000 is a thousand octodecillion in the British system. In the American system, I'm a little unsure how we'd name the number, because I don't know what the number 10^93 is. If 10^93 is something like trenillion, then your number is sextrenillion. But my source (Webster's Dictionary) doesn't give the name for numbers above vigintillion, which is 10^63. See, the American system counts the powers of 1,000, but it doesn't count one of the powers. So it counts the "number of groups of three 0's after 1,000", according to Webster. Anyway, I hope this helps you, and I encourage you to look in a dictionary under "number" to figure out what some more numbers would be called. Of course, most mathematicians would simply leave it as 10^111. Now you see why. Dr.Math
