## What is Roman Numeral Converter XI?

Convert Roman numerals to numbers and back, instantly.

Tap out CXXIII and see 123. Type 2026 and get MMXXVI. One thing, done fast.

DATES, DONE PROPERLY

The Date tab turns any date into Roman numerals — the reason most people need them in the first place:
• Choose DD MM YYYY, MM DD YYYY, or the year on its own
• Pick your separator: · . / — or a plain space
• Copy or share the result in one tap
• Ideal for tattoos, wedding bands, engravings and anniversaries

BUILT FOR THE JOB
• Two-way conversion — numerals to numbers, or numbers to numerals
• Live results as you type, with malformed numerals corrected as you go
• Strict checking: IIII, VV and IC are caught rather than quietly guessed at
• Covers the full standard range, I to MMMCMXCIX (1 to 3999)
• Conversions work with no internet connection
• Full support for light and dark mode

Free to use. Remove the ads with a single one-off purchase — never a subscription.
