      Formula

      Split the whole-number part into groups of three digits, starting from the right
      Read each group as hundreds, tens and ones, then add its name: thousand, million, billion, trillion…
      After a decimal point, say “point” and then each digit in turn

      How to use it

      1. Type the number. Commas and a decimal point are fine.
      2. Read the number in words.
      3. For a check, copy the check-writing line and replace “dollars” with your currency if needed.

      Style rules

      Compound numbers from twenty-one to ninety-nine take a hyphen. American usage leaves out “and” inside whole numbers — one hundred five — while British usage includes it: one hundred and five. This converter follows the American style.

      Forty has no “u”, and ordinals change the last word only: twenty-first, one hundred second, three thousandth.

      Writing a check

      Write the dollars in words and the cents as a fraction over 100: “One thousand two hundred thirty-four and 56/100”. Start at the far left of the line and draw a line through any space left over so nothing can be added.

      Large numbers

      Names follow the short scale used in the US and modern British English: a billion is 10⁹, a trillion 10¹², then quadrillion, quintillion, sextillion, septillion, octillion, nonillion and decillion (10³³). The converter handles whole-number parts of up to 36 digits.
