Roman numeral converter

How to use

Convert Roman numerals and integers in either direction, including dates or delimited lists.

Limits

The converter uses standard subtractive pairs such as IV and CM. An overline multiplies a group by 1,000. Enter an underscore before each overlined letter, or paste the overline itself. Values are limited to 1–3,999,999. Date mode converts each field and preserves separators.
