How to use Number to Roman Numerals

Type your number into the input box — a year like 2026, an age, a chapter number.
Read the Roman numeral instantly: 2026 → MMXXVI.
For dates, convert day, month and year as separate numbers — e.g. 14·2·2026 → XIV · II · MMXXVI.
Click “Copy result” — and for tattoos or engravings, double-check by decoding it back with the reverse tool.

What is Number to Roman Numerals?

A number to Roman numerals converter rewrites an ordinary number using the seven Roman symbols — I (1), V (5), X (10), L (50), C (100), D (500), M (1000) — with the subtractive rule that a smaller symbol before a larger one subtracts: IV is 4, IX is 9, XL is 40, CM is 900.

The subtractive rules are exactly where hand conversion goes wrong: 49 is XLIX (40 + 9), not IL — only I, X and C may be subtracted, and only from the next two symbol steps up. This tool applies the standard rules perfectly, every time.

About the Number to Roman Numerals

Type any number and its Roman numeral appears instantly, using correct standard notation: 2026 → MMXXVI, 1994 → MCMXCIV, 3999 → MMMCMXCIX.

The classic uses: movie and book copyright years (film credits still say MMXXIV), clock faces, Super Bowl and Olympic numbering, monument inscriptions, outline numbering and tattoo designs — dates rendered as numerals are one of the most-requested tattoo formats, and a wrong numeral is permanent. Converting each part of a date (day, month, year) separately gives the standard tattoo layout.

Conversion is instant and local to your browser. The companion Roman Numerals to Number tool decodes existing numerals back to digits.

Frequently Asked Questions

Standard notation subtracts: I before V means 5 − 1. The famous exception is clock faces, which traditionally use IIII for visual balance — both have historical precedent, but IV is the modern standard.

No. Only I, X and C subtract, and each only from the next two steps up (I from V/X, X from L/C, C from D/M). So 49 = XL + IX = XLIX.

MMXXVI — MM (2000) + XX (20) + VI (6). Recent years: 2024 = MMXXIV, 2025 = MMXXV, 1999 = MCMXCIX.

3,999 = MMMCMXCIX with plain symbols, since M can't repeat four times. Larger numbers historically used a bar over symbols to mean ×1000 (V̄ = 5000).

No — the Romans had no symbol for zero; the concept entered European math centuries later via Arabic numerals. Medieval scribes sometimes wrote N (nulla), but it was never part of the numeral system.
