How do Roman numerals work?

Roman numerals use seven symbols: I=1, V=5, X=10, L=50, C=100, D=500, M=1000. When a smaller numeral appears before a larger one, it is subtracted (IV=4, IX=9, XL=40, XC=90, CD=400, CM=900). Otherwise, values are added (VI=6, XI=11).

What is the largest Roman numeral?

The standard system goes up to 3,999 (MMMCMXCIX). Numbers above 4,000 historically used a vinculum (overline bar) to multiply by 1,000, but this is rarely used today.

What year is MMXXIV in Roman numerals?

MMXXIV = 2024. MM = 2000, XX = 20, IV = 4. Roman numerals are still commonly used in movie credits, clock faces, book chapters, and Super Bowl numbering.

Why is 4 written as IV and not IIII?

IV uses the subtractive notation (5-1=4) which is the modern standard. However, IIII (additive notation) is also valid and is commonly seen on clock faces, known as the "watchmaker's four."

The Roman numeral converter instantly translates between standard numbers (1-3,999) and Roman numerals (I-MMMCMXCIX). It uses the subtractive notation standard where IV=4, IX=9, XL=40, XC=90, CD=400, and CM=900 — the system universally accepted in modern usage.

Roman numerals use seven base symbols: I (1), V (5), X (10), L (50), C (100), D (500), and M (1,000). When a smaller value appears before a larger one, it is subtracted; otherwise values are added left to right. The system handles numbers up to 3,999 — beyond that, historical texts used a vinculum (overline bar) to multiply by 1,000, though this is rarely encountered today.

Roman numerals remain surprisingly common in everyday life: clock faces (especially IV vs IIII — the "watchmaker's four"), movie sequel numbering, Super Bowl editions, book chapters and outlines, building cornerstones showing construction year, and formal documents. The year 2024 in Roman numerals is MMXXIV (MM=2000, XX=20, IV=4). Use this alongside our Binary Converter and GCD & LCM Calculator for other number system tools.
