What is the financial 大寫 form for?

大寫 (capital) numbers replace the simple characters 一二三 and units 十百千 with complex ones — 壹貳叁 and 拾佰仟. Because the simple characters are easy to alter with a stroke or two, the complex forms are required on cheques, receipts, and contracts in Taiwan and Hong Kong to guard against fraud.

How is the number grouped?

Chinese groups digits every four places by the myriad scale: 萬 (10,000), 億 (100 million), 兆 (10^12). This differs from Western thousands-grouping, so 1,234,567 reads as 一百二十三萬四千五百六十七.

Why does 零 appear in some numbers?

When a number has an internal zero gap between non-zero digits, Chinese inserts 零 to mark the skipped place — for example 10,086 is 一萬零八十六. The tool adds 零 only where a gap actually exists, never for trailing zeros.

Why is 10 written 十 and not 一十?

In the standard everyday form, a leading 1 in the tens place at the start of a number is dropped, so 10 is 十 and 15 is 十五. In the financial 大寫 form the digit is always written in full (壹拾), because explicitness is the whole point of that style.

Does it run privately?

Yes. Both character styles are generated from built-in tables in your browser. No number you enter is uploaded or stored.

Numbers, written in Traditional Chinese characters

Traditional Chinese writes numbers two ways. The standard form uses the familiar characters 一二三 with units 十百千 for everyday text. The financial 大寫 form uses complex characters such as 壹貳叁 and 拾佰仟 so that amounts on cheques and contracts cannot be altered. This tool produces both from any integer you enter.

How it works

The number is split into four-digit groups, since Chinese counts by the myriad scale rather than by thousands. Within each group the digits take their place units — 十 (ten), 百 (hundred), 千 (thousand) — and the groups are joined by the big units 萬, 億, 兆:

1234567 = 一百二十三萬四千五百六十七
10086   = 一萬零八十六

A 零 is inserted wherever an internal zero gap separates non-zero digits, but never for trailing zeros. In the standard form a leading 1 in the tens place at the start is dropped (十, not 一十); the financial form always writes the digit in full.

Tips and notes

Use the standard form for ordinary writing and the financial 大寫 form whenever the number is money on a legal or banking document — that is exactly the context the complex characters were designed for. Watch the 零 rule: it marks a genuine internal gap (一萬零八十六) and should not appear for round numbers like 一萬 (10,000).
