What Are Roman Numerals?
Roman numerals use seven letters from the Latin alphabet to represent numbers:
| Symbol | Value | Example |
|---|---|---|
| I | 1 | III=3 |
| V | 5 | VI=6 |
| X | 10 | XII=12 |
| L | 50 | LX=60 |
| C | 100 | CX=110 |
| D | 500 | DC=600 |
| M | 1,000 | MM=2,000 |
Add symbols in descending order. Use the standard subtractive pairs when a smaller symbol precedes a larger one:
- VI=5 + 1=6
- IV=5 − 1=4
- XL=50 − 10=40
- XC=100 − 10=90

How Roman Numerals Work
1. Add Descending Values
When symbols run from larger to smaller, add their values: XVII=10 + 5 + 1 + 1=17.
2. Read Subtractive Pairs
The six standard pairs are IV, IX, XL, XC, CD and CM. For example, XL means 50 − 10=40. You cannot subtract any smaller symbol from any larger one: 99 is XCIX, not IC.
3. Combine the Parts
Break 1994 into 1000 + 900 + 90 + 4. These become M + CM + XC + IV: MCMXCIV.
In standard notation, I, X, C and M can repeat up to three times in a row. V, L and D do not repeat. This converter uses IV for four; the clock-face variant IIII is not accepted.
