U+33A3 "㎣" Square Mm Cubed Unicode Character
Unicode Version 17.0
㎣
U+33A3 "㎣" Square Mm Cubed is a precomposed CJK compatibility ideograph that represents the metric volume unit "cubic millimeter," typically used in specialized contexts such as scientific notation, engineering diagrams, or data where a compact representation of "mm³" is required. It belongs to the CJK Compatibility block in Unicode, which includes many such units and characters designed for compatibility with older East Asian character sets, where space constraints or legacy encoding made precomposed forms preferable. While modern systems can render "mm³" using basic Latin letters and a superscript digit, this single character persists in certain technical documentation and typesetting environments to ensure unambiguous rendering.
