About Roman Numerals
Roman numerals are a numeral system originating in ancient Rome, using combinations of letters from the Latin alphabet (I, V, X, L, C, D, M) to represent numbers.
The system is based on seven symbols: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). Numbers are formed by combining these symbols according to specific rules.
Roman numerals are still used today for clock faces, book chapters, movie sequels, and formal documents. This converter handles numbers from 1 to 3,999,999.
