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
