FAQ

Why is the limit 3999?

Standard Roman notation uses M for 1000. Four or more M's become impractical. Historical notations for larger numbers existed but aren't standard.

How is 1994 written?

MCMXCIV: M(1000) + CM(900) + XC(90) + IV(4) = 1994.

Can I use this for years?

Yes, this is commonly used for copyright dates (©MMXXIV = ©2024) and building dedications.

Are there multiple valid representations?

Modern standard uses subtractive notation (IV, IX, etc.). Some historical uses allowed IIII, but this converter uses modern standard form.
