How Chinese capital numerals work
Chinese capital numerals (大写数字) are a formal way of writing amounts on invoices, contracts, checks, and accounting records in China. Instead of ordinary digits, each number is spelled out with a dedicated character — 壹, 贰, 叁, and so on — that's far harder to alter than a simple digit.
The main reason they're required on financial documents is fraud prevention: an ordinary “1” can easily be changed into a “4” or “7” with a stroke of a pen, but a capital character like 壹 (one) can't be turned into 肆 (four) without it being obvious. Banks, tax authorities, and accounting standards in mainland China mandate this format specifically for that reason.
This tool converts any numeric RMB amount — up to two decimal places for jiao/fen, and up to hundreds of billions for the integer part — into the correct capital-numeral string, including the proper placement of 元, 角, 分, and 整.
Frequently asked questions
Why does China require capital numerals on financial documents?
It's a fraud-prevention rule. Ordinary digits like 1, 2, and 3 are easy to alter with an extra stroke, while capital characters such as 壹, 贰, 叁 are visually distinct and much harder to tamper with — so banks, tax bureaus, and accounting standards require them on invoices, checks, contracts, and official receipts.
What's the difference between 小写 and 大写 amounts?
小写 (lowercase) is the everyday numeric form, like ¥1234.56. 大写 (capital) is the formal written-out form used on official documents, like 壹仟贰佰叁拾肆元伍角陆分. They represent the same value — capital numerals are just the tamper-resistant version.
How is an amount like 100.00 written in capital numerals?
100.00 becomes 壹佰元整. The character 整 at the end means “exactly,” signaling there's no jiao or fen (no cents).
What does 整 mean at the end of a result?
整 means the amount is a whole number with no decimal portion — equivalent to writing “.00” but in the formal capital style.
What's the largest amount this tool supports?
Up to 999,999,999,999.99 — just under one trillion yuan, which covers every real-world invoicing, payroll, or contract scenario.
