RMB Capital Amount

Purpose

Chinese RMB amount-to-capital converter following national financial regulation GB/T 17696-1999. Converts Arabic numbers (12345.67) to Chinese capital characters ("壹万贰仟叁佰肆拾伍元陆角柒分整"). Supports yuan/jiao/fen precision, zero handling (consecutive zeros collapsed, integer trailing "整"), negatives ("负" prefix), large amounts (trillions). Common for check writing, invoice issuing, contract amount clauses, financial report capital columns. All conversion runs locally.

Steps

1. Type amount (up to two decimals) on the left

3. "元" or "圆": default "元", can switch to "圆" (traditional bank usage)
4. Integer "整" suffix: 1000 → "壹仟元整"
5. Zero handling: 1001 → "壹仟零壹元", 1010 → "壹仟零壹拾元", 10000 → "壹万元整"

FAQ

Why "壹贰叁" instead of "一二三"?

Anti-fraud. "一" can be altered by adding strokes to look like "二" or "三". "壹" is hard to alter. Financial regulation: invoices, checks, contracts must use capital characters. Correct: 零壹贰叁肆伍陆柒捌玖.

"元" or "圆"?

Both accepted by regulation. "圆" is more traditional (bank checks, old invoices). "元" is modern (new invoices, contracts). Be consistent within a document.

Trailing zero after decimal — write or omit?

Per regulation: integer ends add "整" (100 → "壹佰元整"). With jiao/fen, no trailing "整" (100.50 → "壹佰元伍角"). 100.00: write "壹佰元整" (zero jiao/fen omitted, "整" appended).

How to handle interior zeros?

Consecutive zeros collapse to a single "零": 10001 → "壹万零壹元整" (not "壹万零零零壹元"). 万/亿 positions when zero are omitted: 100000001 → "壹亿零壹元整". Rules are complex — the tool handles per GB standard.

How large can amounts be?

Theoretically unbounded (万, 亿, 万亿, 京, 垓...), but real-world finance rarely exceeds 999 亿 (a single transaction over 10 billion is news). The tool supports up to 9999 万亿 (sufficient for any contract). Beyond shows "amount too large" — likely the input is wrong.

Use cases

• Issuing invoices: amount field requires Chinese capital
• Contract clauses: dual digit + capital representation prevents tampering
• Bank drafts: traditional checks require "amount (capital)"
• Financial reports: reimbursement forms / report amount capital column
• Legal documents: court judgments, mediations with amount clauses

Use cases

Invoicing, contract amount clauses, bank drafts, reimbursement, legal documents. Finance, legal, HR, sales. Zero rules, "整" suffix, large amounts, negatives are the differentiators. Compliant with GB/T 17696-1999.
