How do I convert "one hundred twenty-three" to a number?

Type it into the box and the tool reads 123 instantly. The English parser adds the small words (one, twenty-three) into a sub-hundred bucket, multiplies by 100 when it hits "hundred", and flushes upward on scale words. So "one hundred twenty-three" = 1×100 + 23 = 123, and "twelve thousand three hundred" = 12 × 1000 + 3 × 100 = 12300. Hyphens, mixed case and stray commas are all fine.

Does it handle the British "and", like "two thousand and five"?

Yes. The word "and" is treated as glue and ignored, so "two thousand and five" reads 2005 and "three hundred and seven" reads 307. American style without the "and" gives the same answer, so "two thousand five" is also 2005. You never have to pick a dialect — both parse to the same digits.

Can it do decimals and negative numbers?

Both. Put "point" before the fraction and each following word is read as a single digit: "one point five" is 1.5 and "three point one four" is 3.14. Start the phrase with "negative" or "minus" for a sign, so "negative forty-two" is -42. In Chinese the same works with 点 and 负: "一点五" is 1.5 and "负四十二" is -42.

What Chinese number words are supported?

The Chinese parser reads 十百千万亿, the glue zero 零, and treats 两 the same as 二. So 一百二十三 is 123, 两千零五 is 2005, 一万两千三百 is 12300, 十 alone is 10 and 十五 is 15. A leading 十 with no digit in front means one ten, which is why 十五 reads 15 rather than failing. Bare 二十 is 20 and 二十三 is 23.

What is the difference between 两 and 二, and does the tool care?

They are the same value, 2, but used in different spots: 两 goes before a unit like 两千 (2000) or 两万 (20000), while 二 is used when counting or in tens like 二十 (20). The tool accepts either everywhere, so 两千零五 and 二千零五 both read 2005. You don't have to remember the grammar rule to get the right digits.

Can it read formal capital amounts like 壹贰叁?

Yes, within reason. The formal banking glyphs 壹贰叁肆伍陆柒捌玖 and their units 拾佰仟 are accepted, so 壹佰贰拾叁 reads 123. This covers reading a hand-written cheque amount back into figures. For going the other direction — turning 123 into 壹佰贰拾叁 for an invoice — use the Chinese Numeric Converter, which is built for capital-amount output.

Re-key a spelled-out amount from a contract or cheque

A contract clause reads "the sum of twelve thousand three hundred dollars" and your spreadsheet needs the figure. Paste the words, read 12300, copy, done — no counting digits in your head or miscounting a zero. The same works for a hand-written cheque whose amount is spelled out: type the words and get the number you can reconcile against the numeric box.

Validate that words and figures on a form agree

Invoices and legal forms write the amount twice — once in words, once in figures — precisely so the two can be cross-checked. Drop the word form in here, read the digits, and compare against the printed figure. If "two thousand and five" comes back as 2005 but the box says 2050, you have caught a transposition before it ships.

Parse number words out of transcribed speech

Voice notes and meeting transcripts come back as "we need about three hundred fifty units" rather than 350. When you are cleaning a transcript into structured data, paste each spoken quantity and read the digit value so your notes hold real numbers you can sum and sort.

Read a Chinese capital amount back into figures

A receipt or cheque written 壹佰贰拾叁 needs to land in your books as 123. Type the capital glyphs, read 123, and reconcile. The Chinese parser also handles everyday forms like 一万两千三百 (12300) and 两千零五 (2005), so transcribing any Chinese amount stops being a place-value puzzle.

What this tool does

Turn a number written out in words back into Arabic digits, in English and in Chinese. Type "one hundred twenty-three" and read 123; type "two thousand and five" and read 2005; type "negative forty-two" and read -42; type "one point five" and read 1.5. The English parser handles hundred, thousand, million and billion, the British "and", hyphenated tens like twenty-three, mixed case and stray commas. The Chinese parser reads 十百千万亿, the 零 separator, 两 as well as 二, the 负 sign and a 点 decimal tail, so 一百二十三 becomes 123 and 负四十二 becomes -42. Leave the toggle on auto and it detects the language for you, or pin it to English or Chinese. One click copies the digits. Everything runs in your browser; nothing you type is uploaded or logged, and the shareable link reopens on the same phrase.

Common pitfalls

Writing the decimal part as words bigger than nine. After "point" each word must be a single digit, so "one point five" works but "one point fifteen" does not — say "one point one five" for 1.15. The same rule applies in Chinese after 点.
Stringing bare Chinese digits with no unit, like 一二三. Chinese is positional through units (十百千), not digit-by-digit, so 一二三 is not a number — write 一百二十三 for 123. The tool returns empty rather than guessing 123 from loose digits.
Forgetting the sign goes first. "Forty-two negative" will not parse; the sign word (negative / minus / 负) must lead the phrase, as in "negative forty-two" or 负四十二.

Privacy

The two parsers — English and Chinese — are plain JavaScript that runs in your browser tab. Nothing you type is uploaded, and there is no logging of the words or the resulting digits. The one caveat: the shareable URL encodes your input phrase in the query string, so pasting a "share link" into chat records that phrase in the recipient server's access log. For a confidential contract or cheque amount, use the copy button and paste the digits rather than sharing the URL.
