About this app

Turn any number from 1 to 3,999 into Roman numerals, or read a Roman numeral back as a number. Every answer comes with a breakdown - MCMXCIV shown as M (1000) + CM (900) + XC (90) + IV (4) - so you can see exactly how it works.

Only the standard form of Roman numerals is accepted, so an incorrect numeral like IIII or IC is flagged instead of being given a misleading value. A quick reference of the seven symbols and the subtraction rule is always on screen.
