Type a number into a browser-based Roman numeral converter and it returns the Roman numeral, so 2026 becomes MMXXVI. It also converts the other way, and because it runs on your device it is an instant, offline-friendly way to handle dates, clock faces, chapter numbers and outlines.
Roman numerals use I, V, X, L, C, D and M for 1, 5, 10, 50, 100, 500 and 1000. Symbols are added together left to right, except when a smaller symbol sits before a larger one, which means subtract, so IV is 4 and IX is 9. That subtraction rule is where hand conversion goes wrong, which is why a converter that applies it correctly is handy for anything beyond the simplest numbers.
Roman numerals persist in copyright years on films, clock and watch faces, monarch and sequel names, book chapters and outline headings. Converting 2026 gives MMXXVI, and reading a numeral like MCMLXXXIV back as 1984 is the reverse job the tool also handles. Standard Roman numerals top out in the low thousands, which the converter respects.
MMXXVI. That is MM for 2000, XX for 20, and VI for 6.
The subtraction rule: a smaller symbol before a larger one is subtracted, so IV is 5 minus 1.
