Convert numbers to Roman numerals or Roman numerals back to regular numbers — handy for clock faces, chapter numbers, or movie sequel titles. The number 1994 converts to MCMXCIV, while MMXXVI converts back to 2026 — the subtractive notation, like IV for 4 instead of IIII, is what makes Roman numeral conversion trickier than it first looks.
