Fraction 1 by 6 (⅙) is the Unicode character at U+2159 in Number Forms. Official name: VULGAR FRACTION ONE SIXTH. It is one precomposed fraction glyph — not the three characters 1/6.
Remember

CSS escape \2159
Meaning vulgar fraction one sixth (1/6)
Not the same 1/6 (three chars) · ⅕ (1/5) · ⅚ (5/6)
Prefer ⅙ in HTML for readable markup. You can also use ⅙, ⅙, or type ⅙ in a UTF-8 document.

Math: 6 ⅙ = 1
How It Works
1. Named:⅙ is the HTML5 name for U+2159 → ⅙.
2. Hex:⅙ inserts the same code point by hexadecimal value.
3. Decimal: same code point as 8537 → ⅙. Same visual as named/hex.
4. CSS: use \2159 in content (not an HTML entity). #point::after appends ⅙.
5. Typed: paste ⅙ in a UTF-8 document when you need the one-sixth glyph as one character.
Pitfalls & Tips
Common mistakes when working with fraction 1 by 6.
Name
Prefer ⅙
The named entity is clear and standard. Avoid inventing names like &onesixth;.
1/6
Not three characters
Typing 1/6 creates three code points. ⅙ is one Number Forms character.
⅚
Not five sixths
Five sixths is ⅚ (U+215A). Use it when you mean 5/6, not 1/6.
Font
Font coverage
Some fonts omit Number Forms fractions. If ⅙ is missing, fall back to 1/6 or a font with Number Forms coverage.
CSS vs HTML
Do not mix escapes
\2159 belongs in CSS strings. ⅙ / ⅙ / ⅙ belong in HTML.
a11y
Add accessible text
Screen readers may not announce ⅙ clearly. Prefer aria-label="one sixth" or nearby prose when the fraction carries meaning.
Semicolon
End references
Always finish entities with ; — write ⅙, not &frac16.
