U+339D "㎝" Square Cm Unicode Character
Unicode Version 17.0
㎝
U+339D "㎝" Square Cm is a single typographic character that represents the unit "cm²" or square centimeter, often used as a shorthand in technical, scientific, or mathematical contexts where space or formatting constraints are a concern. It is part of the CJK Compatibility block, a set of characters originally encoded for compatibility with East Asian character sets that contained precomposed squares for units and abbreviations. Its purpose is to allow a compact, two-character-width representation of "square centimeter" without requiring the separate rendering of the letter 'c', 'm', and a superscript '2', ensuring consistent alignment in text, especially in Chinese, Japanese, or Korean documents.
