Big numbers in Chinese

The manner in which large numbers are broken down in Chinese is a little different from English. Unlike in English, where large numbers are broken down by the number of thousands they have, Chinese forms numbers between 10,000 and 100,000,000 based off of how many tens of thousands they have (with another set of rules for numbers 100,000,000 onwards that will be explained later). While the structure can be difficult to grasp for some learners, there are some easy ways to remember how to form these big numbers.

Different Units

Mandarin has two units that English doesn't have (or at least, it has unique words for these units, whereas English describes them with combinations of other units). These are:

Ten Thousand - (wàn)

(wàn) comes up the most often and is the largest stumbling block for most people learning Mandarin numbers. In English, numbers are usually broken up into chunks of three digits. Because of (wàn), it's easier to break numbers up into groups of four in Mandarin. In English, we split "twelve thousand" numerically into "12,000" (chunks of three digits). Split it the Chinese way, "1,2000," and the Chinese reading "一万两千" (one wan and two "thousand" = yīwàn liǎngqiān) makes more sense.

One way to remember how to write out numbers 10,000 through 99,999 in Chinese characters is that in Chinese, the comma is (mentally) moved one digit to the left. For example, 11,000 could be thought of in tens of thousands as "1,1000," with (wàn) replacing the comma, and then what's left written as 一千 (yīqiān): 一万一千 (yīwàn yīqiān).

One Hundred Million - 亿 ()

After 99,999,999, there is yet another new numerical unit, 亿 (), which is used to express "hundred million." A number like 1,101,110,000 would be written out as "十一亿一百一十一万 (shíyī yì yībǎi yīshí-yī wàn)." Again, an easier way to translate between the two methods is to write the number out in English, move the comma one digit to the left, and then insert the appropriate characters in their respective places, replacing the commas.

A Shortcut

One more simple way to remember how to correctly write out large numbers is to pick one or two numbers and just memorize them. One million, for example, is 一百万 (yībǎi wàn). If you can memorize that, then going to 一千万 (yīqiān wàn) is way easier and faster, since you don't have to count all those zeroes.
