Roman Numerals Guide — Symbols, Rules & Conversion

Roman numerals use seven letters to represent numbers: I (1), V (5), X (10), L (50), C (100), D (500), and M (1,000). Numbers are formed by combining these symbols, generally from largest to smallest, and adding their values — so MMXXVI = 1000 + 1000 + 10 + 10 + 5 + 1 = 2026. The system originated in ancient Rome and is still widely used today for clock faces, book chapters, movie release years, monarch and pope names (Elizabeth II, Pope Francis), and event numbering like the Super Bowl and Olympic Games.

The key rule is subtractive notation: when a smaller symbol appears before a larger one, it's subtracted. So IV = 4 (5−1), IX = 9 (10−1), XL = 40, XC = 90, CD = 400, and CM = 900. This keeps numerals compact — 1999 is MCMXCIX, not the cumbersome IIII-style. Standard Roman numerals max out at 3,999 (MMMCMXCIX) because there's no single symbol for 5,000 or beyond. For larger numbers, a bar (vinculum) over a numeral multiplies it by 1,000; this converter represents that extended range so you can convert years and large values accurately.

The Seven Symbols

I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000. Memorize with: "I Value Xylophones Like Cows Dig Milk."

Subtractive Pairs

IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900. A smaller symbol before a larger one means subtract.

📅

Common Years

2024 = MMXXIV. 2025 = MMXXV. 2026 = MMXXVI. 2000 = MM. 1999 = MCMXCIX. 1984 = MCMLXXXIV.

Super Bowl Numbers

Super Bowl 50 used "50" not L. SB LV = 55, LVI = 56, LVII = 57, LVIII = 58, LIX = 59, LX = 60.

Roman Numerals FAQ

How do you write 2026 in Roman numerals? ▾

2026 in Roman numerals is MMXXVI. It breaks down as MM (2000) + XX (20) + VI (6) = 2026. Recent years: 2024 = MMXXIV, 2025 = MMXXV, 2027 = MMXXVII. This is one of the most common conversions for tattoos and anniversary jewelry.

What is the largest number in Roman numerals? ▾

Using standard symbols, the largest number is 3,999 = MMMCMXCIX, because you can't have four M's in a row and there's no symbol above M. For larger numbers, Romans used a vinculum (a bar over a numeral) to multiply by 1,000 — so an overlined V means 5,000. This converter supports the extended range up to 3,999,999 using that convention.

Why is 4 written as IV and not IIII? ▾

Standard Roman numerals use subtractive notation: IV (5−1 = 4) is shorter and is the official modern form. However, IIII does appear historically — famously on many clock faces, where IIII is used instead of IV for visual balance and tradition. Both represent 4, but this converter outputs the standard IV form.

How do I read Roman numerals? ▾

Read left to right, adding values, but subtract when a smaller symbol precedes a larger one. For MCMXCIV: M (1000) + CM (900) + XC (90) + IV (4) = 1994. Start with the leftmost symbols (largest values) and work right. Our converter shows a full breakdown so you can see exactly how each part contributes.
