Classic Numerals for Modern Use
From movie release dates and sports events to legal documents and formal outlines, Roman numerals are still widely used today. Our converter provides a reliable way to translate standard Arabic numerals into their Latin equivalents and vice versa, ensuring your dates and labels are historically accurate.
Rules of Roman Numerals
- Repetition: A letter can be repeated up to three times (e.g., III = 3, IV = 4).
- Addition: If a smaller value follows a larger one, they are added together (e.g., VI = 5 + 1 = 6).
- Subtraction: If a smaller value precedes a larger one, it is subtracted (e.g., IX = 10 - 1 = 9).
Frequently Asked Questions
By standard convention, Roman numerals go up to 3,999 (MMMCMXCIX). Larger numbers require different notation systems (like a bar over the letter) that are less commonly used.
Traditionally they are written in uppercase (e.g., XIV), but many modern tools and documents also accept lowercase (e.g., xiv). Our tool handles both.
