Free Roman Numeral Converter
Numbers, years and dates to Roman numerals. Free, no signup
A Roman numeral converter that does more than basic conversion. It converts both ways (number to Roman and Roman to number) and supports values up to 3,999,999 using overline (vinculum) notation. It updates live as you type and flags invalid numerals like IIII or VV. It also shows a symbol-by-symbol breakdown, so you learn how each numeral is built. Extras include a date converter for birthdays and tattoos, a reference chart, copy buttons and history. No signup.
Hi everyone! Thanks for checking out the Roman Numeral Converter.
Why I built it: People still use Roman numerals everywhere, like movie credits, clock faces, book chapters, Super Bowl names and tattoo dates. But most converters only handle small numbers, give no explanation, and accept wrong inputs like “IIII” without any warning.
The problem: People want a fast, correct answer, and students want to understand how the numeral is built.
How it evolved: It began as a simple number-to-Roman converter. Then I added reverse conversion with live validation, so mistakes are caught as you type. Next came the symbol-by-symbol breakdown, which turned it into a learning tool. Many people asked about dates for tattoos and wedding invites, so I added a full date converter with a “Use today” button. Finally, I added overline support for numbers up to 3,999,999, plus a reference chart and history.
It’s 100% free, with no signup. What do you use Roman numerals for? Let me know in the comments!
