U+2159 "⅙" Vulgar Fraction One Sixth Unicode Character
Unicode Version 17.0
⅙
U+2159 "⅙" Vulgar Fraction One Sixth is a precomposed typographic glyph representing the numerical value of one divided by six, commonly used in recipes, measurements, and other contexts where a simple, single character is preferred over constructing the fraction from separate numbers like "1/6". It belongs to the Number Forms Unicode block and is designed to maintain consistent visual alignment and readability in text, particularly in documents that require a clean, proportional spacing of fractions. This character is distinct from the separate digit and slash combination, as it is encoded as a single entity for ease of use in digital text processing.
