U+33B2 "㎲" Square Mu S Unicode Character
Unicode Version 17.0
㎲
U+33B2 "㎲" Square Mu S is a precomposed CJK compatibility ideograph that represents the unit of time "microsecond," where the Greek letter mu (μ) denotes the metric prefix micro (one millionth) and S stands for second. This character was included in Unicode specifically for compatibility with older East Asian text encodings that created a single square glyph to represent this measurement unit, allowing it to occupy one character width in monospaced or legacy systems. It is most commonly used in technical and scientific contexts, particularly in Japanese or Chinese text layouts, to express very short time intervals without requiring separate spacing for the mu and S components.
