中文的萬級單位名稱：個、萬、億、兆、京、垓、杼、穰、溝、澗、正、載、極、恆河沙、阿僧祇、那由他、不可思議、無量、大數。每一級單位相差一萬倍

是不是開始連看中文數字都覺得有點頭昏眼花了呢? 郭老師幫各位轉貼這個有趣的英文數字介紹，還有遠遠幾萬倍於兆的數字呢XD Enjoy it!

And let’s learn math in English!

數字的單位

Million, Billion, Trillion...

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
