Writing amounts in words
Cheques, contracts, notarised documents and many invoices state an amount twice, in figures and in words, so that a changed digit cannot pass unnoticed. A few conventions matter:
- British usage puts “and” after hundreds (one hundred and five); American usage often drops it in formal writing. This tool includes it.
- Tens and units are hyphenated: twenty-one, ninety-nine.
- On a cheque, cents are written as a fraction of 100 after the whole amount: one hundred and 56/100 dollars. Draw a line through any space left after the words so nothing can be added.
- The scale is short: million = 10⁶, billion = 10⁹, trillion = 10¹².
- Capitals are common on legal documents: ONE THOUSAND TWO HUNDRED AND THIRTY-FOUR.
Reading the outputs
In words is the plain spoken form, with the currency and cents if chosen. Cheque style writes the cents as a fraction, which is what banks expect on the amount line. Capitals is the same text in upper case with hyphens removed, for forms that are filled in by hand or typed in block letters.
Questions
How do I write 1,000,000 in words?
One million. With a currency: one million dollars, or on a cheque: one million and 00/100 dollars.
Is it “one hundred five” or “one hundred and five”?
Both are correct; “and” is standard British and common in American speech, while American formal and cheque writing often omits it. This tool includes the “and”; delete it if your bank prefers the other form.
How are cents written on a cheque?
As a fraction of 100 after the whole amount: “twelve and 50/100 dollars”. The “Cheque style” output produces exactly that.
What is the largest number supported?
Up to 999 quintillion (10²¹ − 1), which is far beyond any amount on a document.
