About this tool

Roman numerals use seven letters: I=1, V=5, X=10, L=50, C=100, D=500 and M=1000. Letters are added from largest to smallest, so VIII is 5+3=8. A smaller letter before a larger one is subtracted, so IV is 4 and IX is 9.

Only I, X and C can be subtracted, and only from the next two larger letters. A letter is not repeated more than three times in a row, so 4 is IV and not IIII. The usual limit is 3999, because there is no standard symbol for 5000.

Formula

  • Subtractive pairs: IV=4, IX=9, XL=40, XC=90, CD=400, CM=900.
  • Example: 1994 = M (1000) + CM (900) + XC (90) + IV (4) = MCMXCIV.

Examples

  • 1 = I
  • 4 = IV
  • 9 = IX
  • 14 = XIV
  • 40 = XL
  • 90 = XC
  • 400 = CD
  • 1994 = MCMXCIV
  • 2024 = MMXXIV
  • 3999 = MMMCMXCIX

Tips

  • Years are common: 2026 is MMXXVI.
  • Letters can be typed in lowercase.
  • Non-standard forms such as IIII or IC are rejected, because they are not the standard way to write those numbers.
