How MCMXLVIII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 1948 separately and joining the pieces gives MCMXLVIII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Thousands | 1 | 1,000 | M |
| Hundreds | 9 | 900 | CM |
| Tens | 4 | 40 | XL |
| Ones | 8 | 8 | VIII |
Reading it back, left to right:
- M = 1,000 → running total 1,000
- CM = 900 (M minus C) → running total 1,900
- XL = 40 (L minus X) → running total 1,940
- V = 5 → running total 1,945
- I = 1 → running total 1,946
- I = 1 → running total 1,947
- I = 1 → running total 1,948
Why MCMXLVIII has 9 letters
Every year from 1900 to 1999 begins with MCM (1,900); the rest of MCMXLVIII after MCM — XLVIII — spells out 48. Of the 201 years from 1900 to 2100, 6 have a longer numeral and 179 a shorter one.
The rules MCMXLVIII follows
- Largest to smallest. MCMXLVIII uses the symbols M, C, X, L, V and I (9 characters in all), and the values never increase from left to right except inside a subtractive pair.
- Subtraction. CM (900) and XL (40) are subtractive pairs: a smaller symbol in front of a larger one is taken away from it. Only six pairs are allowed — IV, IX, XL, XC, CD and CM — and MCMXLVIII uses two of them.
- Repetition. III repeats I three times. I, X, C and M may repeat up to three times in a row; V, L and D never repeat.
Common mistakes when writing 1948
- MDCCCCXLVIII — wrong because standard numerals never repeat a symbol four times; 900 is written CM. The correct form is MCMXLVIII.
- MCMXXXXVIII — wrong because standard numerals never repeat a symbol four times; 40 is written XL. The correct form is MCMXLVIII.
The year 1948 in Roman numerals: where it appears
- Film and TV credits. Copyright lines at the end of films and TV programs of the period commonly gave the year in numerals — a 1948 production might end with “Copyright MCMXLVIII.”
- An Olympiad year. 1948 is the year of the Games of the XIV Olympiad — London.
- On a calendar. 1948 was a leap year, with 366 days, and January 1 fell on a Thursday. A full date such as July 4, 1948 is often written VII · IV · MCMXLVIII.
