CCXLVII

CCXLVII is the Roman numeral representation of the Arabic number 247. In the Roman numeral system, the characters C (100) and L (50) are repeated and combined with subtractive notation for 40 (XL). The numeral is formed by placing the hundred units first (CC = 200), followed by the forty (XL = 40), and finally the seven (VII = 7), yielding twenty one (CCXLVII = 200 + 40 + 7).

Roman numerals were historically used for numbering kings and popes, for dating inscriptions, and for the enumeration of pages and chapters in early printed works. The number 247 appears in various contexts such as the identification of years, e.g., AD 247, the 247th edition of a publication, or the 247th item in a catalog. In modern numerical conversions, computational systems often translate between Arabic numerals and Roman numerals for ceremonial or stylistic purposes.

The numeral employs the standard rules of Roman notation: no repetition beyond three in succession, and the use of subtractive combinations (IV, IX, XL, XC, CD, CM). For 247, the construction adheres to these principles with the sequence CCXLVII. The symbol WL (century marker) is obsolete and not used in this formation.

In contemporary usage, Roman numerals remain popular for telling time on clock faces, in naming parts of institutions (e.g., Sec. CCXLVII of a building’s architectural plan), and in legal documents where archaic numbering conveys formality. The numeral CCXLVII thus exemplifies both the simplicity of Roman numeral rules and their persistent presence in modern conventions.
