How MCMIII is built

Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 1903 separately and joining the pieces gives MCMIII:

PlaceDigitValueNumeral
Thousands11,000M
Hundreds9900CM
Tens00— (zero has no symbol)
Ones33III

Reading it back, left to right:

  • M = 1,000 → running total 1,000
  • CM = 900 (M minus C) → running total 1,900
  • I = 1 → running total 1,901
  • I = 1 → running total 1,902
  • I = 1 → running total 1,903

Why MCMIII has 6 letters

Every year from 1900 to 1999 begins with MCM (1,900); the rest of MCMIII after MCM — III — spells out 3. Of the 201 years from 1900 to 2100, 100 have a longer numeral and 55 a shorter one.

The rules MCMIII follows

  • Largest to smallest. MCMIII uses the symbols M, C and I (6 characters in all), and the values never increase from left to right except inside a subtractive pair.
  • Subtraction. CM (900) is a subtractive pair: 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 MCMIII uses one 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 1903

  • MDCCCCIII — wrong because standard numerals never repeat a symbol four times; 900 is written CM. The correct form is MCMIII.

The year 1903 in Roman numerals: where it appears

  • Cornerstones and public buildings. Buildings, bridges and monuments from the early 20th century often have their completion year carved as a numeral, so MCMIII may be cut into a date stone or lintel from 1903.
  • On a calendar. 1903 was not a leap year (365 days), and January 1 fell on a Thursday. A full date such as July 4, 1903 is often written VII · IV · MCMIII.
