Roman numeral converter
Convert numbers to Roman numerals and back (1 to 3999).
I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000. A smaller symbol before a larger one is subtracted (IV = 4, XC = 90). Standard form reaches 3999.
How it works
Roman numerals add symbols from large to small; a smaller symbol placed before a larger one is subtracted.
