Fun Facts from the Scriptorium
Explore the fascinating history and rules of this ancient numbering system.
There Was No Zero
The Roman system had no character to represent the concept of "zero." This is one of the main reasons it was eventually replaced for complex mathematics.
The Subtractive Principle
Writing IV (4) instead of IIII is called the subtractive principle. It was used for efficiency but wasn't standardized until long after the Roman Empire.
The Vinculum for Large Numbers
To write numbers larger than 3999, Romans would place a bar (vinculum) over a numeral to multiply it by 1,000. So, a V would represent 5,000.
Frequently Asked Questions
Clarification on the converter's rules and capabilities.
What is the largest number I can convert?
This generator follows the standard modern convention, which limits conversions to the number 3,999 (MMMCMXCIX). This is because the rule of not repeating a symbol more than three times prevents the creation of 4,000 (MMMM).
Why is 4 written as IV and not IIII?
This is the "subtractive principle," where a smaller numeral placed before a larger one is subtracted. So, IV is 5 - 1 = 4. This notation is more compact than the additive version (IIII). The same rule applies to IX (9), XL (40), XC (90), CD (400), and CM (900).
Can I use the generated text in commercial projects?
Yes. The converted text itself is not subject to copyright. The fonts used (Inter, Playfair Display, Cinzel Decorative) are from Google Fonts and are licensed under the Open Font License, which permits both personal and commercial use freely.
