Sobre Esta Calculadora
Roman numerals follow a subtractive notation system — when a smaller value appears before a larger one (like IV or XL), it's subtracted rather than added. That logic makes manual conversion error-prone, especially for numbers in the 800–900 and 1800–1900 ranges where multiple subtractive pairs appear in sequence.
This converter handles the complete valid range of standard Roman numerals (1 through 3,999) in both directions. Type an integer and get the Roman numeral; type Roman numerals and get the integer. It validates input and flags numbers outside the standard range.
Roman numerals still appear regularly in everyday life: film and TV copyright notices, clock faces, book chapter headings, Super Bowl numbering, and architectural inscriptions.
O Conversor de Números Romanos traduz qualquer número para sua forma romana e vice-versa.
