U+33AF "㎯" Square Rad over S Squared Unicode Character
Unicode Version 17.0
㎯
U+33AF "㎯" Square Rad over S Squared is a single CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the unit "rad/s²," specifically the radian per second squared used to measure angular acceleration. It was included in Unicode for compatibility with legacy East Asian character encoding standards, where such precomposed units were often needed for compact text layout in technical or engineering contexts. This character allows the unit to be displayed as a single glyph rather than as a sequence of separate characters, ensuring consistent formatting in historical documents or computer systems that rely on these older encodings.
