U+33A4 "㎤" Square Cm Cubed Unicode Character
Unicode Version 17.0
㎤
U+33A4 "㎤" Square Cm Cubed is a precomposed CJK compatibility ideograph that represents the unit of volume "cubic centimeter," often abbreviated as cm³. It was included in the Unicode standard primarily for compatibility with legacy East Asian character encoding systems, where such composite units were frequently used in technical and scientific contexts. Despite its appearance as a single glyph, its usage has largely been superseded by standard ASCII representations like "cm³" in modern digital typography, though it may still appear in specialized documents or software designed for older character sets.
