二 vs. 两
èr vs. liǎng

Both of them mean “two”.

1. 二 is used in reading a number.
(1) 他出生于1982年。
(2) 我的邮编是三二二九二二。

In mathematical formulae, 2 is pronounced 二.

2. 二 is used in the ordinal number.
(1)我二叔已经回去了。
(2) 今年二月份我去了一次他那儿。

3. When there is a measure word (including 百、千、万、亿，etc.) 两 is used, e.g. 两个人 liǎnggè rén, 两个教室 liǎnggè jiàoshì, 两种方法 liǎng zhǒng fāngfǎ, etc. But 百, 千, 万, 亿 can also used together with 二, e.g. 二百 èr bǎi (200). In a sequence of numbers, the bigger digits can be modified by 两 while the small digits by 二, e.g. 两万二千二百 liǎng wàn èr qiān èr bǎi (22,200). As an exception, both 二 and 两 can be used to modify 位.
(1) 两（二）位这边请。
(2) 请问二（两）位想要点什么？

4. Before units of length, capacity and weight, either 二 or 两can be used, e.g. 两（二）公斤 liǎng (èr) gōngjīn, 二（两）里 èr (liǎng) lǐ.

5. In polysyllabic words or four-character phrases, 二 indicates order or number, e.g. 一分为二 yī fèn wéi èr (one divides into two; there are two sides to everything), 说一不二 shuō yī bù èr (stand by one’s word; while 两 indicates two sides, e.g. 两全其美 liǎngquán qí měi (satisfactory to both sides), 两败俱伤 liǎng bài jù shāng (both sides suffer, neither side gains), etc.

二 can be used as an ordinal number,the second 第二， but we don't say 第两，but as a cardinal number 二 can't be followed by a measure word, in contrast, we must put a measure word after 两，for example, 两个苹果，but we can't say 二个苹果。

“两" для количества (сколько?) и указания времени в "сейчас два часа"

“二"一般是数数用，”两“主要是说着顺嘴，”两“用的范围广。例如，我这有两只鸟。那有两盆花。吃俩苹果吧。

For your information, 两 is also a unit of Chinese weights and measures, 1 两= 1 斤= 50 grams.

sorry, 1斤=10两=500 grams. 1两= 1/10 斤= 50 grams.

「二」的常用用法是數字或表示「順序」的意思，例如：第二名、第二個

「兩（两）」的常用用法：

有「一雙、一對（pair）」的意思，例如：兩隻手、兩條腿

表示數量的習慣用法，例如：兩點、兩天、兩個
