The Roman Numeral Converter works both ways: type a number to get its Roman numeral, or type a Roman numeral to get the number. Below you can write any date in Roman numerals — popular for tattoos and anniversaries — and find the century of a year. The page also has a chart of Roman numerals from 1 to 100, hundreds and thousands.

How to convert Roman numerals

Type a number from 1 to 3999 in the Number box — the Roman numeral appears next to it.
Or type a Roman numeral such as XIX — the number appears instantly. Lowercase letters work too.

How to read Roman numerals

There are seven Roman numerals: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500 and M = 1000. They are written from largest to smallest and added up: XVI = 10 + 5 + 1 = 16. When a smaller numeral comes before a larger one, it is subtracted: IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900. The same numeral is not repeated more than three times in a row, so 4 is IV rather than IIII. There is no zero.

Dates in Roman numerals

For a date, each part is converted separately: 23 October 2026 becomes X.XXIII.MMXXVI in month-day-year order. Pick the separator you like — dots, middle dots, spaces or slashes.
