Reading and writing Roman numerals
Roman numerals still turn up on clock faces, film credits, book chapters, Super Bowl names and monarchs. There are only seven symbols: I (1), V (5), X (10), L (50), C (100), D (500) and M (1,000).
The easiest way to write a number is place by place. For 2026, write 2,000 as MM, 20 as XX and 6 as VI, then join them: MMXXVI. The table under the result shows this split for any number you enter.
Reading works the other way. Add the symbols from left to right, but when a smaller one comes before a larger one, subtract it. In MCMXCIV, M = 1,000, CM = 900, XC = 90 and IV = 4, so it is 1994.
Only six subtractive pairs are standard: IV, IX, XL, XC, CD and CM. That is why 99 is XCIX rather than IC, and why the converter rejects forms like IIII or VX.

How this is calculated
Formula: Roman numerals
write each place value with I, V, X, L, C, D and M, largest firstWhat the symbols mean
- I, V, X1, 5, 10.
- L, C50, 100.
- D, M500, 1,000.
- IV, IX, XL, XC, CD, CM4, 9, 40, 90, 400, 900: a smaller symbol before a larger one is subtracted.
Good to know
- A symbol is never repeated more than three times in a row.
- For numbers in words, use the number to words converter.

How do you write 2026 in Roman numerals?
MMXXVI: MM is 2,000, XX is 20 and VI is 6.
What is MCMXCIV?
1994: M is 1,000, CM is 900, XC is 90 and IV is 4.
Why is 4 written IV and not IIII?
Modern Roman numerals use subtraction to avoid four of the same symbol. Some clock faces still show IIII by tradition.
What is the largest Roman numeral?
3,999 (MMMCMXCIX) in the standard form. Larger numbers used a bar over a symbol to multiply it by 1,000.
Is there a zero in Roman numerals?
No. The Romans had no symbol for zero.
