# How do you write the number 180 in Chinese: 一百八十 or 一八零?

How do you write the number 180 in Chinese?

I have tried searched on google and I believe it is 一百八十 but some people are telling me it is 一八零 I have heard from multiple people on each side. I would just like confirmation on how it generally it is written from someone who is more knowledgable.

If a number is referring to an amount or order that can be counted, use 一百八十

If a number is referring to a digital identity, use 一八零 (e.g. serial number, phone number)

They're both correct, but used in different contexts. In any case, for writing, we'd almost always just write the numbers 180.

Tang Ho♦ and Becky 李蓓♦ are right, and the numeral form is also used to describe height.

The 183cm（一米八三） has the short form 一八三(yāo and yī both ok).

There is a recently popular joke on Chinese Internet: Some people are so proud of their height that they never miss a chance to show off it. So you can often see username like "张三(183.5cm" (it is high enough in Asia) . A girl and a boy are talking about the school exam score, the girl says “我考了90分，你多高？”(My score is ..., and how about you?), the boy answers “一八三”(Obviously not a score).

Both can be used at any place if 180 means one hundred and eighty. But "一百八十" is more official than "一八零".

When you use 180 in phone numbers, it does not mean 一百八十 (one hundred and eighty) because it is used with other numbers like you can not say 780 as senven and eighty or senventy eight and zero.
