How MCMXLVII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 1947 separately and joining the pieces gives MCMXLVII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Thousands | 1 | 1,000 | M |
| Hundreds | 9 | 900 | CM |
| Tens | 4 | 40 | XL |
| Ones | 7 | 7 | VII |
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
Why MCMXLVII has 8 letters
Every year from 1900 to 1999 begins with MCM (1,900); the rest of MCMXLVII after MCM — XLVII — spells out 47. Of the 201 years from 1900 to 2100, 22 have a longer numeral and 147 a shorter one.
The rules MCMXLVII follows
- Largest to smallest. MCMXLVII uses the symbols M, C, X, L, V and I (8 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 MCMXLVII uses two of them.
- Repetition. II repeats I two 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 1947
- MDCCCCXLVII — wrong because standard numerals never repeat a symbol four times; 900 is written CM. The correct form is MCMXLVII.
- MCMXXXXVII — wrong because standard numerals never repeat a symbol four times; 40 is written XL. The correct form is MCMXLVII.
The year 1947 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 1947 production might end with “Copyright MCMXLVII.”
- On a calendar. 1947 was not a leap year (365 days), and January 1 fell on a Wednesday. A full date such as July 4, 1947 is often written VII · IV · MCMXLVII.
