Notes on the Letter Cases used to write out in words the number above:

  • 1: Lowercase: only lowercase letters are used. Example: 'seventy-six and two tenths'.
  • 2: Uppercase: only uppercase letters are used. Example: 'SEVENTY-SIX AND TWO TENTHS'.
  • 3. Title Case: the first letters of the words are capitalized, except for certain short words, such as articles, conjunctions and short prepositions, 'a', 'an', 'the', 'and', 'but', 'for', 'at', 'by', 'to', 'or', 'in', etc. Example: 'Seventy-Six and Two Tenths'.
  • 4. Sentence case: only the first letter of the first word at the beginning of the sentence is capitalized. Example: 'Seventy-six and two tenths'.
  • 5. Start Case: the first letter of each word is capitalized without any exception. Example: 'Seventy-Six And Two Tenths'.
  • 6. Camel Case: text has no spaces nor punctuation and the first letter of each word is capitalized except for the very first letter in the series. Example: 'seventySixAndTwoTenths'.
  • 7. Hyphen Case: text has no spaces nor punctuation and the words are delimited by hyphen. Example: 'seventy-six-and-two-tenths'. Hyphen Case can be lowercase or uppercase.

General Notes on Writing Out Numbers:

  • 1: It's correct to hyphenate all compound numbers from twenty-one (21) through ninety-nine (99). The hyphen is the minus sign, as in 'thirty-four' (34).
  • 2: In American English, unlike British English, when writing out natural numbers of three or more digits, the word 'and' is not used after 'hundred' or 'thousand': so it is 'one thousand two hundred thirty-four' and not 'one thousand two hundred and thirty-four'.
  • 3. Use commas when writing in digits numbers above 999: 1,234; 43,290, 1,000,000 etc.


How to convert ordinal numerals to words in (US) American English, how to write them out using letters instead of numerals

How to write out ordinal numbers (those denoting order) in words?

Most ordinal numbers end in "th", so just add "th" to the end of the cardinal number (those denoting quantity, ex: 1 one, 2 two, 3 three, 4 four, ... etc.):

  • cardinal: 4 = four → ordinal: 4th = fourth
  • cardinal: 7 = seven → ordinal: 7th = seventh
