U+2236 "∶" Ratio Unicode Character
Unicode Version 17.0
∶
U+2236 "∶" Ratio is a mathematical symbol used to represent a ratio or a relationship between two quantities, often appearing in contexts such as mathematics, science, and typography to denote a comparison of numbers or magnitudes. It is distinct from the similar-looking colon punctuation mark, as it is specifically designed for mathematical notation and is typically centered vertically to align with other operators. In Unicode, it falls under the Mathematical Operators block, and its usage helps avoid ambiguity in technical writing where a colon might otherwise be misinterpreted.
