Number to Words Converter — Cheque Writing

Writing numbers and amounts in words

Numbers are written out in words on cheques, legal contracts, invoices and formal letters, because words are harder to alter than digits and remove any doubt about the amount. English groups digits in threes: each group is spelled as a number from one to nine hundred ninety-nine and followed by its scale word — thousand, million, billion, trillion and so on. So 1,234,567 becomes “one million two hundred thirty-four thousand five hundred sixty-seven”. Compound numbers between twenty-one and ninety-nine take a hyphen.

The Words style reads decimals digit by digit after “point”, as in “twelve point zero five”. Currency words spells both parts, such as “one thousand two hundred thirty-four dollars and fifty-six cents”, with correct singular and plural units for dollars, euros, pounds and pence, and rupees and paise. Ordinal turns whole numbers into positions — first, twelfth, twenty-first, one hundredth — which is useful for dates, rankings and formal documents.

How to write a cheque or check

On a cheque the amount is written twice: in digits in the box and in words on the line. The usual format writes the whole amount in words followed by the cents as a fraction over one hundred: “One Thousand Two Hundred Thirty-Four and 56/100 Dollars”. If there are no cents, write “and 00/100”. Start writing at the very left of the line and draw a line through any remaining space so nobody can add words. If the digits and words disagree, banks usually treat the words as the legal amount, which is why getting them right matters.

American usage normally reserves “and” for the decimal part, while British usage also places it after hundreds, as in “one hundred and five”; use the checkbox to switch. Title Case is the most common style on cheques, but sentence case, lowercase and uppercase are also available.
