1948 in Roman Numerals

How to write 1948 in Roman numerals, step by step

Roman numerals are built from largest value to smallest. Split 1948 into place values first: 1000 + 900 + 40 + 5 + 3.

Now swap each part for its symbols: 1000 becomes M, 900 becomes CM, 40 becomes XL, 5 becomes V, 3 becomes III. Written together that is MCMXLVIII.

The pairs XL and CM must stay in that order. XL means "one before 50", so it is read as 40.

• 1000 = M (M is 1000)
• 900 = CM (CM is the subtractive form for 900)
• 40 = XL (XL is the subtractive form for 40)
• 5 = V (V is 5)
• 3 = III (I is 1, written 3 times)

Is MCMXLVIII written correctly?

Yes. MCMXLVIII is the standard modern form of 1948. 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 MCMXLVIII on a keyboard

Roman numerals are ordinary capital letters, so you can type MCMXLVIII directly: M, C, M, X, L, V, I, I, I. 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.

Using 1948 as a date

Written as a full date, 1948 usually appears at the end: 4 July 1948 becomes IV • VII • MCMXLVIII, with dots or dashes separating day, month and year.

If you are having MCMXLVIII engraved or tattooed, check the spacing and the character shapes with the artist first. Roman numerals are long, and MCMXLVIII is 9 characters, so it needs more room than the four digits do.
