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
  • cardinal: 10 = ten → ordinal: 10th = tenth
  • cardinal: 19 = nineteen → ordinal: 19th = nineteenth
  • cardinal: 100 = one hundred → ordinal: 100th = (one) hundredth
  • cardinal: 1,000 = one thousand → ordinal: 1,000th = (one) thousandth

Exceptions:

  • cardinal: 1 = one → ordinal: first = 1st
  • cardinal: 2 = two → ordinal: second = 2nd
  • cardinal: 3 = three → ordinal: third = 3rd
  • cardinal: 5 = five → ordinal: fifth = 5th
  • cardinal: 8 = eight → ordinal: eighth = 8th
  • cardinal: 9 = nine → ordinal: ninth = 9th
  • cardinal: 12 = twelve → ordinal: twelfth = 12th
  • cardinal: 20 = twenty → ordinal: twentieth = 20th
  • cardinal: 30 = thirty → ordinal: thirtieth = 30th
  • cardinal: 40 = forty → ordinal: fortieth = 40th
  • cardinal: 50 = fifty → ordinal: fiftieth = 50th
  • cardinal: 60 = sixty → ordinal: sixtieth = 60th
  • cardinal: 70 = seventy → ordinal: seventieth = 70th
  • cardinal: 80 = eighty → ordinal: eightieth = 80th
  • cardinal: 90 = ninety → ordinal: ninetieth = 90th

Here there are a couple of the main ordinal numbers, from 1st up to 19th, you can find a longer list in the full article:

  • cardinal: 1 = one; → ordinal: 1st = first;
  • cardinal: 2 = two; → ordinal: 2nd, second;
  • cardinal: 3 = three; → ordinal: 3rd, third;
  • cardinal: 4 = four; → ordinal: 4th, fourth;
  • cardinal: 5 = five; → ordinal: 5th, fifth;
  • cardinal: 6 = six; → ordinal: 6th, sixth;
  • cardinal: 7 = seven; → ordinal: 7th, seventh;
  • cardinal: 8 = eight; → ordinal: 8th, eighth;
  • cardinal: 9 = nine; → ordinal: 9th, ninth;
  • cardinal: 10 = ten; → ordinal: 10th, tenth;
  • cardinal: 11 = eleven; → ordinal: 11th, eleventh;
  • cardinal: 12 = twelve; → ordinal: 12th, twelfth;
  • cardinal: 13 = thirteen; → ordinal: thirteenth;
  • cardinal: 14 = fourteen; → ordinal: 14th, fourteenth;
  • cardinal: 15 = fifteen; → ordinal: 15th, fifteenth;
  • cardinal: 16 = sixteen; → ordinal: 16th, sixteenth;
  • cardinal: 17 = seventeen; → ordinal: 17th, seventeenth;
  • cardinal: 18 = eighteen; → ordinal: 18th, eighteenth;
  • cardinal: 19 = nineteen; → ordinal: 19th, nineteenth;
