Roman Numerals for Outlines and Documents
Generate the correct Roman numerals for document outlines, chapters, and formal section numbering.
Common values
Roman numeral rules: I=1, V=5, X=10, L=50, C=100, D=500, M=1000.
Subtractive notation: IV=4, IX=9, XL=40, XC=90, CD=400, CM=900. Standard numerals max out at MMMCMXCIX (3999).
Vinculum: a bar over a numeral multiplies it by 1000 (V̅ = 5000, X̅ = 10000, M̅ = 1,000,000), extending the range to 3,999,999.
Documents tips
Traditional document outlines use Roman numerals for top-level sections: I, II, III, IV. Generate any numeral and verify it's correct before use.
Book chapter numbering often uses Roman numerals. Generate numbers for long books — XXIV (24), XLVIII (48), or even C (100) for long works.
Legal documents, contracts, and formal reports commonly use Roman numerals for section headings. Verify each one here to avoid the common IV/VI confusion.
The "from-Roman" mode lets you decode a section number you're looking at — useful when navigating a document to find a specific numbered section.
