Understanding the Number to Words Converter
Writing a cheque correctly requires spelling out the amount in words on the second line — "One Thousand Two Hundred Thirty-Four Dollars and 56/100 Cents" — while the figures go on the first line. Get it wrong and the bank honors the written words over the numbers, or refuses the cheque entirely. This converter handles that specific formatting automatically, along with standard English word conversion for any integer up to the quadrillions.
Accounts-payable staff who write checks by hand, small business owners printing payment slips, legal document drafters writing out contract values, teachers generating word-form exercises, and anyone double-checking a large number they are about to write on a cheque all reach for this tool. The standard mode converts a number to plain English (1,234,567 → "One Million Two Hundred Thirty-Four Thousand Five Hundred Sixty-Seven"). Cheque mode adds the currency formatting, handling both the integer dollar amount and the cents as a fraction.
Conversion uses a pure recursive JavaScript algorithm — no libraries. It handles scale words (thousand, million, billion, trillion, quadrillion), the correct hyphenation of compound tens (Twenty-One through Ninety-Nine), and the "and" connector before hundreds that bank style guides require.

Frequently Asked Questions
How do I write a cheque amount correctly?
Write the dollar amount in words on the "Pay to the order of" line, then add "and XX/100" for the cents — for example, "One Hundred Fifty Dollars and 75/100". Draw a line through any remaining space to prevent alteration. The written words are legally authoritative if they differ from the numeral box.
What is the largest number this tool converts?
The converter handles integers up to 999,999,999,999,999 (999 quadrillion) — well beyond any everyday financial or scientific figure. Beyond that, JavaScript integer precision limits apply.
Why are the tens hyphenated (Twenty-One vs Twenty One)?
The Chicago Manual of Style, AP Style Guide, and most grammar authorities require a hyphen in compound numbers from twenty-one to ninety-nine. "Twenty-One" is the correct written form; "Twenty One" is non-standard. The cheque format especially requires this, as handwriting ambiguity could otherwise alter the meaning.
Does this work for currencies other than USD?
The cheque mode outputs "Dollars and XX/100 Cents" by default, which is the US banking convention. For other currencies, use Standard mode to get the plain words and then add your own currency label — the word conversion itself (e.g., "One Thousand Two Hundred") is currency-neutral.
