RMB Uppercase Converter

Why a separate tool for 人民币大写

Need the amount in English, Spanish or another language instead? The number to words converter writes cheque wording in seven of them.

Our number to words converter already writes Chinese cheque amounts. But anyone filling in a bill in mainland China runs into more questions than one line of output can answer. Does 1,680.32 need a 零 after 元? Is ten yuan 壹拾元 or just 拾元? What do you write in the date box for the 10th of January? And which little square does the ¥ go in on a deposit slip?

This page answers all of those. It follows the rules banks in mainland China actually check, the People's Bank of China guidance on filling in bills and settlement documents (正确填写票据和结算凭证的基本规定). If a teller would hand the cheque back, the tool shouldn't produce it.

Before building it I tried the converters people already use. They're fine for everyday amounts. The best known one stops at 千亿, none of them told me that some 零 are optional, and I didn't find one that wrote the cheque date, which is the bit people get wrong most often.

What you get

• The amount in capitals. 1,234.56 becomes 人民币壹仟贰佰叁拾肆元伍角陆分.
• The figure the way it goes in the small amount box, ¥1,234.56.
• A row of boxes like the ones printed on a cheque or 进账单, labelled 亿 千 百 十 万 千 百 十 元 角 分, with every digit in its square and the ¥ right in front.
• The date in capitals, for example 贰零贰陆年壹拾壹月壹拾贰日.

Amounts can run to 16 digits before the point, so up to 9999万亿. Nobody writes a cheque that size, but contract totals and budget lines sometimes need the wording, so there's room for it.

How the 零 rules work

Most hand-written 大写 mistakes are about 零. Laid out, the rules are short:

• A zero in the middle gets one 零. 1,409.50 is 壹仟肆佰零玖元伍角整.
• Several zeros in a row still get only one 零. 6,007.14 is 陆仟零柒元壹角肆分.
• If the 角 is zero and the 分 isn't, 零 after 元 is required. 16,409.02 is 壹万陆仟肆佰零玖元零贰分.
• Zeros at the end of the yuan part just vanish. 1,000 is 壹仟元整.

Then there's the optional one. When the yuan digit is 0 and 角 follow, as in 1,680.32, the rules accept both 壹仟陆佰捌拾元零叁角贰分 and 壹仟陆佰捌拾元叁角贰分. The tickbox under the amount controls it. I leave it on, because an extra 零 makes it harder for anyone to squeeze a digit in later, and stopping that is the whole point of 大写. If your company template does it the other way, untick it.

When 整 goes on the end

An amount that stops at 元 gets 整 after it: 壹拾元整. Some people write 正 instead, and banks take that too. If it stops at 角, adding 整 is allowed but not required. This tool writes it, as in 伍角整, since a closed-off amount is safer. When there's a 分, nothing comes after it.

And ten is always 壹拾, never plain 拾. You'd say 十块 out loud, but on a bill the 壹 stops someone turning 拾元 into 伍拾元.

Writing the date on a cheque

The issue date on a 支票 or 汇票 has to be in capitals as well, and it has its own trap. For January, February and October the month gets a 零 in front: 零壹月, 零贰月, 零壹拾月. Days 1 to 10, plus the 20th and the 30th, get a 零 too: 零伍日, 零壹拾日, 零贰拾日. Days 11 to 19 start with 壹, as in 壹拾伍日. So 10 January 2026 is 贰零贰陆年零壹月零壹拾日.

Banks can refuse a cheque with the date written the wrong way, and they do look. The date box starts on today, which is usually the date you're writing anyway. Change it and the capitals update.

The box layout

Paper forms such as the 进账单 and many cheques have a row of boxes for the figures, with a unit printed over each one. The ¥ goes in the box just before the first digit, so nothing can be added in front, and every box from there to 分 gets a digit, zeros included. For ¥0.50 that means ¥ under 十, 0 under 元, 5 under 角 and 0 under 分. The grid on this page shows exactly that, with the 角 and 分 boxes shaded so you can match it against the form in front of you.

A few real situations

Making the invoice itself? The invoice generator builds the whole document, and the 大写 line can go into its notes.

A shop owner in Shenzhen writes a 转账支票 to a supplier for 38,005.00. That's 叁万捌仟零伍元整, one 零 for the two zeros in the middle. Easy to get wrong by hand at the end of a long week.

A bookkeeper fills in 收据 and 报销单 all day, each with a 大写 line. Type, copy, paste, next one.

The finance team at a foreign company needs the Chinese wording for a contract with a mainland partner, and nobody in the office reads Chinese well enough to check it. The tool gives the version that follows the bank rules, with the figure underneath so they can be sure the right number went in.

A student revising for the 会计 exam checks their answers to the 大写 exercises, including the dates, which the textbooks love to test.

Typing the amount

Receipts usually want the amount in capitals too, so you can paste the result straight into the receipt generator.

Type it however it comes to you: 1234.56, 1,234.56, ¥1234.56 or full-width digits from a Chinese keyboard. Commas, spaces and the ¥ sign are ignored. Use a dot for the decimal point. More than two decimals is refused unless the extra digits are zeros, because RMB stops at 分 and a bank won't take 厘 on a cheque. Negative amounts get an error too, since a bill never carries a negative 大写 amount.

Mistakes I see all the time

Writing 两 instead of 贰. Everyone says 两千块, but 两 isn't one of the bank characters, and neither are 廿 or 毛. A cheque with 两仟元整 on it can be rejected.

Using the everyday digits 一 二 三. They're the easiest to alter (一 becomes 二 or 三 with a stroke or two), which is exactly why the formal set exists.

Leaving a gap between 人民币 and the first character. The amount should start right after 人民币 so nothing can be slipped in. When you copy the result from here, there's no space to worry about.

Fixing a mistake on the cheque. You can't. If the amount or the date is wrong on a cheque, the bank won't accept a correction, even a neat one with a stamp. Tear it up and write a new one. That's another reason to check the wording here first.

Writing 元 when the form wants 圆. Both are accepted on mainland bills, so the tool sticks with 元, which is what most people use.

Privacy and limits

Everything runs in your browser. The amount and the date never leave the page, there's no sign-up, and nothing is stored. When you're typing payroll figures or a client's invoice totals, that's worth something.

One honest limit: this follows mainland China rules for RMB. Hong Kong and Taiwan write cheques with traditional characters and their own habits (Taiwan uses 圓 or 元, for instance), so if that's you, compare with your bank's own sample first.
