Convert numbers to Roman numerals and vice versa.
How It Works
The Roman Numeral Counter uses a straightforward method to convert between numbers and Roman numerals. For numbers to Roman numerals, it breaks down the number into its largest possible Roman symbols (like M for 1000, C for 100, etc.) and subtracts the value until the number reaches zero. For Roman numerals to numbers, it adds the value of each symbol, adjusting for cases where a smaller symbol precedes a larger one (like IV for 4 or IX for 9). Here’s a quick example:
- 42 → XLII: 40 (XL) + 2 (II)
- XLII → 42: 40 (XL) + 2 (II)
