Convert numbers into formal RMB uppercase amounts.
RMB Uppercase online
Convert an amount in yuan into the formal Chinese financial uppercase wording （大写金额） — 123.45 becomes 壹佰贰拾叁元肆角伍分 — for invoices, cheques, contracts and receipts where digits are not allowed to stand alone.
How to use this tool
- Enter the amount as a plain number, for example 1234.56.
- Click Run Tool. The amount is rounded to the 分 (two decimals) and written out in financial uppercase characters.
- Copy the wording into your document exactly as generated — every character counts.
Common uses
Filling in Chinese invoices （发票）, cheques and bank forms, writing the amount clause of a contract in words as fraud protection, preparing reimbursement and payment vouchers, and double-checking a hand-written 大写 amount against the numeric figure.
How it works
The converter follows the standard financial rules: digits become 零壹贰叁肆伍陆柒捌玖， places take 拾佰仟 within each four-digit section and 万 / 亿 between sections, and the amount ends with 元， then 角 and 分， with 整 appended when there are no 角分. Zero handling follows the convention accountants check: a single 零 marks a skipped place inside a section rather than one 零 per empty digit, and a whole section of zeros collapses correctly. Amounts from 0 up to just under one trillion yuan are supported; the value is rounded to the nearest 分 first.
Worked example
1001 converts to 壹仟零壹元整 — one 零 for the empty hundreds place, none for the tens because the rule inserts 零 once per run of zeros, not per digit. 100.05 converts to 壹佰元零伍分: with zero 角， the wording still carries 零 before 伍分， which is the detail handwritten amounts most often get wrong and auditors most often circle. And 0 itself gives 零元整.

Frequently asked questions
Why does financial Chinese use special characters at all?
防篡改. Ordinary 一二三 are a stroke away from being altered （一 → 十， 二 → 三）; the financial forms 壹贰叁 are complex enough that tampering shows. That is why Chinese banks and tax documents require amounts in 大写 alongside the digits.
What does 整 mean at the end?
"Exactly, and no more" — it certifies the amount ends at 元 with no 角 or 分. When there are 角分, the wording ends at 分 without 整 （肆角伍分）, and a zero 角 with non-zero 分 keeps a 零 as the bridge （零伍分）.
Can it convert negative amounts or amounts over a trillion?
No — the supported range is 0 to just under 10^12 yuan, the span Chinese financial documents use （亿 tops out the section system here). Negative amounts in practice are written as text （负） by hand on the rare forms that need them.
How are more than two decimals handled?
The amount is rounded to the 分 (nearest cent) before conversion, matching how money settles. 10.005 becomes 10.01 → 壹拾元零壹分 under standard rounding of the stored decimal.
Is my amount uploaded?
No. Conversion runs in your browser; nothing is sent anywhere.
