How to write 144 in Roman numerals, step by step
Roman numerals are built from largest value to smallest. Split 144 into place values first: 100 + 40 + 4.
Now swap each part for its symbols: 100 becomes C, 40 becomes XL, 4 becomes IV. Written together that is CXLIV.
The pairs IV and XL must stay in that order. IV means "one before 5", so it is read as 4.
- 100 = C (C is 100)
- 40 = XL (XL is the subtractive form for 40)
- 4 = IV (IV is the subtractive form for 4)
Is CXLIV written correctly?
Yes. CXLIV is the standard modern form of 144. A valid Roman numeral never repeats a symbol more than three times in a row, never repeats V, L or D at all, and only ever subtracts I, X or C, and only from the next two larger symbols.
Those rules are what keeps a number to a single accepted spelling, so a reader never has to guess.
How to type CXLIV on a keyboard
Roman numerals are ordinary capital letters, so you can type CXLIV directly: C, X, L, I, V. Nothing special is required and it will work in any font, any document and any web form.
Unicode also contains dedicated Roman numeral characters such as Ⅰ, Ⅴ, Ⅹ, Ⅼ, Ⅽ, Ⅾ and Ⅿ. They exist for typesetting East Asian text and they look almost identical, but search engines, spell checkers and screen readers handle the plain letters better, so the letters are usually the right choice.
Where you will see CXLIV
Numbers of this size turn up as chapter and page numbers in front matter, as list levels in outlines, as monarch and pope regnal numbers, and in the names of recurring events such as Super Bowl finals.
If you are using CXLIV in a document, keep it in capitals. Lowercase roman numerals (cxliv) are conventionally reserved for preliminary page numbering and sub-lists.
