Calculate your scenario

The whole-number part is split into groups of three digits from the right; each group is written as hundreds, tens and ones and followed by its short-scale word (thousand = 10^3, million = 10^6, billion = 10^9, trillion = 10^12).

Default worked example. Edit the inputs to calculate your scenario.

Default worked example

In words one thousand two hundred thirty-four
Digits grouped 1,234
Scale used Short scale; largest scale word: thousand
Word count 5
Character count 36

Split 1,234 into groups of three (1 | 234), read each group with its short-scale word.

How to use the calculator

Type the number, pick words, cheque or ordinal style, then pick the capitalization you need.

What the result means

1,234 is written "one thousand two hundred thirty-four": one group of thousands and then 234.

Formula and units

The whole-number part is split into groups of three digits from the right; each group is written as hundreds, tens and ones and followed by its short-scale word (thousand = 10^3, million = 10^6, billion = 10^9, trillion = 10^12). Numbers 21–99 are hyphenated and no "and" is inserted. Decimals are read digit by digit after "point", cheque style writes the cents as a fraction of 100, and ordinal style changes the last word (one → first, twenty → twentieth).

Worked examples

1,234 in words: Number (commas and spaces allowed): 1234 digits; Style: words; Capitalization: lower.
Example result: In words: one thousand two hundred thirty-four; Digits grouped: 1,234; Scale used: Short scale; largest scale word: thousand; Word count: 5; Character count: 36.

$1,500,000.25 written for a cheque: Number (commas and spaces allowed): 1500000.25 digits; Style: cheque; Capitalization: sentence.
Example result: In words: One million five hundred thousand dollars and 25/100; Digits grouped: 1,500,000.25; Scale used: Short scale; largest scale word: million; Word count: 8; Character count: 52.

Limitations and common mistakes

English short scale only (a billion is 10^9, not the long-scale 10^12). Whole part up to 999,999,999,999,999 and up to 6 decimals; decimals are read exactly as typed, so trailing zeros are kept in word style. Cheque style uses dollars and needs at most 2 decimals; it is a spelling aid, not advice on cheque rules at any bank. Ordinals take whole numbers of zero or more.

Writing "one thousand two hundred and thirty-four dollars" on a cheque and then leaving the cents line blank; write the cents as xx/100 even when they are 00.
