What does this tool do?
The Number to Words converter turns a numeric figure into written English words, for example rendering 1234567 as "One million two hundred thirty-four thousand five hundred sixty-seven." It is handy for writing cheques, drafting invoices and contracts, and anyone who needs to spell out amounts in English documents.

Cardinal, ordinal, and currency modes
Three output formats are available. Cardinal mode writes the plain number (for example "forty-two"). Ordinal mode produces a ranking word ("forty-second") and correctly handles irregular forms such as first, second, and twelfth. Currency mode spells out the whole part as dollars and the fractional part as cents, which is especially useful when filling in a cheque. All conversions support numbers up to roughly 999 billion and prefix negative values with the word "negative."
Frequently asked questions
What is the largest number it can convert?
It handles values up to just under one trillion (999,999,999,999). Beyond that limit it shows a "Number too large" message rather than producing an incorrect result.
How does ordinal mode handle a number like 12?
It produces "twelfth." The tool recognises irregular ordinal forms such as first, second, third, fifth, ninth, and twelfth, and applies a -th ending to all the regular cases.
How are decimal numbers handled?
In cardinal mode only the integer part is written. In currency mode the fractional part is rounded to two places and added as cents, so 19.99 becomes "... dollars and ninety-nine cents."
