The Words to Numbers converter translates written English number words into their numeric digit equivalents instantly. Type 'forty-two' and get 42. Enter 'one thousand two hundred and fifty' and get 1,250. Results update as you type.
Numbers appear as words in a surprising number of practical contexts: transcribed audio and speech-to-text output, legal contracts and formal documents (where amounts are spelled out for clarity), survey responses with free-text fields, financial reports, invoice descriptions, and natural language data pipelines.
The converter handles integers of any size, cardinal numbers (one, two, three), ordinal numbers (first, second, hundredth), informal spoken forms ('a hundred', 'a thousand', 'a dozen' — where 'a' is treated as 'one'), hyphenated compound numbers (twenty-one through ninety-nine), and negative numbers introduced by 'negative' or 'minus'.
For extracting or converting numbers embedded within longer sentences, use this tool together with the Find & Replace or Regex Tester tool to isolate the number expression before converting it.
Everything runs locally in your browser. Your input is never sent to a server and no sign-up is required.

Frequently Asked Questions
What number words does it support?
It supports English cardinal numbers (one, two, three…), ordinal words (first, second, third…), informal forms (a hundred, a dozen, a thousand), hyphenated compounds (twenty-one through ninety-nine), negative numbers (negative five, minus three), and large scale words (million, billion, trillion). Numbers must be written in standard English form.
Can it convert numbers embedded in a sentence?
The tool is optimised for converting a complete number expression entered on its own (e.g. 'forty-two thousand') rather than finding and replacing numbers inside long prose. For extracting number words from sentences, combine this tool with the Find & Replace tool to isolate the expression first.
Does it handle ordinal numbers like 'first' or 'twenty-third'?
Yes — ordinal words (first, second, third, twenty-third, hundredth, etc.) are recognised and converted to their numeric equivalents (1, 2, 3, 23, 100). The output is the plain number without an ordinal suffix.
What is the maximum number it can convert?
The converter handles numbers up to the trillions without issue. Very large numbers (quadrillions and beyond) depend on your browser's JavaScript number precision limits but work correctly for most practical inputs.
Why would numbers appear as words in a document?
Legal documents spell out amounts for clarity and to prevent tampering (e.g. 'five thousand dollars'). Transcribed speech and speech-to-text output often produce number words rather than digits. Survey free-text responses and formal writing style guides also prefer spelled-out numbers in certain contexts.
Does 'a' count as 'one' (e.g. 'a hundred')?
Yes — the indefinite article 'a' is treated as 'one' in number expressions. So 'a hundred' converts to 100, 'a thousand' to 1000, and 'a dozen' to 12.
