About the Roman numeral converter
Roman numerals are built from seven letters, each with a fixed value: I is 1, V is 5, X is 10, L is 50, C is 100, D is 500, and M is 1000. Converting a number to Roman numerals uses a greedy algorithm — repeatedly find the largest value from a table that still fits into what's left, append its symbol, and subtract that value, continuing until nothing remains.
That table includes six special two-letter combinations that use subtractive notation to avoid writing the same letter four times in a row: 900 is CM, 400 is CD, 90 is XC, 40 is XL, 9 is IX, and 4 is IV. Without these, 4 would awkwardly be IIII instead of the standard IV, and 40 would be XXXX instead of XL. The full descending value table this calculator uses is 1000 (M), 900 (CM), 500 (D), 400 (CD), 100 (C), 90 (XC), 50 (L), 40 (XL), 10 (X), 9 (IX), 5 (V), 4 (IV), 1 (I).
Converting the other direction — from Roman numerals back to a number — works by scanning the letters left to right and adding each symbol's value, except when a smaller-value symbol appears directly before a larger one, in which case it's subtracted instead. For example, in IX the I (1) comes before the larger X (10), so it's subtracted: 10 − 1 = 9. In XI the I comes after the X, so it's added: 10 + 1 = 11.
This calculator supports whole numbers from 1 to 3999. That upper limit isn't arbitrary — standard Roman numerals don't have a repeatable symbol for 5000 or higher without adding a vinculum (an overline that multiplies a symbol's value by 1000), a notation this calculator doesn't attempt to render, so 3999 (MMMCMXCIX) is the largest number it will convert.
Roman numerals still show up in everyday places worth recognizing: movie copyright years, Super Bowl numbering, book chapter and volume numbers, clock faces, and the names of monarchs and popes (like Elizabeth II or Louis XIV). Being able to convert quickly in either direction is handy whenever you run into one of these without a clear key.
Roman numeral converter questions
How to convert between numbers and Roman numerals.
How do you convert a number to Roman numerals?
Use a greedy algorithm: starting from the largest value (1000 for M), repeatedly subtract the largest value that still fits into the remaining number and append its symbol, until nothing is left. For example, 14 becomes X (10) + IV (4) = XIV.
How do you convert Roman numerals to numbers?
Scan the letters left to right, adding each symbol's value unless a smaller-value symbol comes directly before a larger one, in which case you subtract it instead. For example, IX is 10 − 1 = 9, while XI is 10 + 1 = 11.
What is the highest number you can write in Roman numerals?
Using standard letters (I, V, X, L, C, D, M) without special notation, the highest number is 3999, written as MMMCMXCIX. Numbers beyond that traditionally require a vinculum (an overline) to multiply a symbol's value by 1000.
Why is 4 written as IV instead of IIII?
Roman numerals use subtractive notation for six values — 4 (IV), 9 (IX), 40 (XL), 90 (XC), 400 (CD), and 900 (CM) — to avoid repeating the same symbol four times in a row. IV means "one less than five," which is shorter and clearer than IIII.
How do you write 1994 in Roman numerals?
1994 is MCMXCIV: M (1000) + CM (900) + XC (90) + IV (4) = 1994. You'll recognize this from film copyright notices of that year.
What year is MMXXIV in Roman numerals?
MMXXIV is 2024: MM (2000) + XX (20) + IV (4) = 2024.
