Every Chinese number is built from just a handful of digit and unit characters. Each has an everyday form and a formal banker's form (大写, dàxiě) used on cheques and contracts.

The everyday characters 一 二 三 are just one, two, and three horizontal strokes — and a dishonest person could add strokes to turn 一 (1) into 二 (2) or 三 (3) on a cheque or contract. To stop this, China has used a parallel set of visually complex formal numerals (大写数字, dàxiě shùzì) on financial documents for centuries.

• Cheques & bank drafts — the amount is written in formal numerals so it cannot be altered.
• Contracts & invoices — formal amounts carry legal weight.
• Receipts (发票) — official tax receipts require the 大写 amount.

Example: a cheque for ¥1,234 would show 壹仟贰佰叁拾肆 rather than the casual 一千二百三十四. The converter above gives you both forms side by side.

How do you write 1234 in Chinese?

1234 is 一千二百三十四 (yī qiān èr bǎi sān shí sì) in everyday Chinese, and 壹仟贰佰叁拾肆 in formal banker's numerals. Type any number above to see both.

What are banker's numerals (大写)?

A formal set of number characters (壹 贰 叁 …) used on cheques, contracts, and official receipts so the amount cannot be altered. They prevent fraud because they are far harder to add strokes to than 一 二 三.

What is 万 (wàn)?

Chinese groups large numbers by ten-thousand, not thousand. 10,000 = 一万 (yī wàn), 100,000 = 十万 (shí wàn), and 100,000,000 = 一亿 (yī yì). The converter handles these automatically.

二 (èr) or 两 (liǎng) for "two"?

Use 二 for counting and in the ones/tens place; use 两 before big units and measure words (两百, 两千, 两个). Both are correct.

Can I convert Chinese numerals back to digits?

Yes — paste everyday or formal Chinese numerals and click Convert to get the Arabic number, plus the other forms and Pinyin.
