Number to Words Converter
This number to words converter writes a figure out in English, in four styles: plain words, ordinal words, the numeric ordinal form, and a currency amount in eight currencies. The currency style produces the amount-in-words line that cheques, invoices and contracts carry — a convention that exists because a figure in digits alone can be altered after signing, while words cannot easily be. Decimals in words mode are read digit by digit, the way people say them aloud, so 12.05 becomes Twelve Point Zero Five rather than Twelve and Five Hundredths.
How it works
Type a number and read it back in English. Currency mode produces the amount-in-words line that cheques, invoices and contracts carry — the wording that exists so a figure cannot be altered after signing.
Decimals in Words mode are read digit by digit, the way people say them aloud: 12.05 becomes “Twelve Point Zero Five” rather than “Twelve and Five Hundredths”.

How to convert numbers to words
- Type or paste a number — commas in the input are ignored.
- Pick a style: words, ordinal words, an ordinal number, or a currency amount.
- Choose the capitalisation you need and copy the result.
Why cheques and contracts spell out the amount
A figure written only in digits can be altered after signing — a 1 becomes a 4, a zero gets appended. Spelling the amount out in words makes that far harder, which is why the convention has survived in banking and law long after the paperwork went digital. The trailing word Only serves the same purpose: it marks the end of the amount so nothing can be added after it.
How decimals are read
In words mode the digits after the point are read individually, the way people actually say them aloud — 12.05 becomes “Twelve Point Zero Five” rather than “Twelve and Five Hundredths”. In currency mode the fraction is treated as minor units instead, so 12.05 becomes twelve of the major unit and five of the minor.
Ordinals
Only the last word changes when a number becomes an ordinal: “Twenty-One” becomes “Twenty-First”, and “One
Million” becomes “One Millionth”. The numeric form follows the usual English rule, where 11, 12 and 13 take
th despite ending in 1, 2 and 3.
Common use cases
- Writing the amount-in-words line on a cheque, invoice or receipt.
- Drafting a contract clause where a figure must appear in both forms.
- Producing ordinal text for dates, rankings or document numbering.
Frequently asked questions
Why do cheques spell out the amount in words?
Because a figure in digits can be altered after signing — a 1 becomes a 4, a zero gets appended. Words are far harder to change, which is why banking and law kept the convention. The trailing word "Only" marks the end so nothing can be added after it.
How are decimals read?
In words mode the digits after the point are read individually, the way people say them aloud, so 12.05 becomes "Twelve Point Zero Five". In currency mode the fraction is treated as minor units instead — twelve of the major unit and five of the minor.
Which currencies are supported?
US, Australian and Canadian dollars, euros, pounds, Indian rupees, Bangladeshi taka and Japanese yen, each with its own major and minor unit names and correct plurals.
How do ordinals work?
Only the last word changes: "Twenty-One" becomes "Twenty-First" and "One Million" becomes "One Millionth". The numeric form follows the usual rule where 11, 12 and 13 take "th" despite ending in 1, 2 and 3.
How large a number can it handle?
Up to just under a quadrillion. Beyond that, grouped digits are clearer than words, so the number is returned formatted rather than spelled out.
