Frequently Asked Questions

What can I convert here?

Numbers between Arabic numerals (1–3,999) and Roman numerals — in both directions, each with a place-value breakdown, symbol reference, and a live converter on every page.

How do Roman numerals work?

The system has seven symbols: I (1), V (5), X (10), L (50), C (100), D (500), and M (1,000). Symbols are added together — except in six subtractive pairs (IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900), where a smaller symbol before a larger one is subtracted.

What is the largest Roman numeral?

In the standard system without overlines, the largest representable number is 3,999, written as MMMCMXCIX. Historically, a vinculum (overline) was used for larger values, but that is not part of the standard system used here.

Is there a zero in Roman numerals?

No. The classical system has no symbol for zero — it was a counting system for positive quantities. The Latin word 'nulla' (nothing) was occasionally used, but not as a positional digit in the way Arabic zero is.

Are the results exact?

Yes. Converting between Arabic and Roman numerals is pure integer math and perfectly exact — the same value, just written a different way.
