Numbers to words converter

Convert any number — whole or decimal, positive or negative, up to decillion — into English words. Switch between plain spelling, a spoken-currency reading, and the standard US check-writing format. Letter-case is configurable for any of them.

Numbers to words

Spelled out
One Thousand Two Hundred Thirty-Four and 56/100

The three modes

  • Words — pure English. 1234.56 → "one thousand two hundred thirty-four point five six".
  • Currency — reads the integer part as the major unit and the fractional part as the minor unit (cents, paise, pence, etc.) for the chosen currency. 1234.56 USD → "one thousand two hundred thirty-four dollars and fifty-six cents".
  • Check writing — US bank-check format. The dollar amount is spelled out, then "and", then the cents as a fraction "NN/100". $1,234.56 → "One Thousand Two Hundred Thirty-Four and 56/100".

Letter case

Each mode has a sensible default — Title Case for check writing, lowercase for words, sentence-style for currency — but you can override it. The case button you pick applies to whatever's currently in the output.

FAQ

Should I use "and" between hundreds and tens? (e.g. "one hundred and twenty")

British English commonly inserts "and" — "one hundred and twenty-three". American English usually drops it. This converter follows American style by default ("one hundred twenty-three") to match standard US bank check format.

What about Indian numbering (lakh, crore)?

This converter uses the Western short scale (thousand, million, billion). Indian-style lakh / crore output is not currently supported here — let us know if you'd like it.
