U+33AE "㎮" Square Rad over S Unicode Character
Unicode Version 17.0
㎮
U+33AE "㎮" Square Rad over S is a CJK (Chinese, Japanese, and Korean) compatibility ideograph used primarily in East Asian typography to represent the unit "rad per second," a measure of angular velocity in physics and engineering. This square-form symbol condenses the phrase "rad/s" into a single character for compact display in technical documentation, such as in formulas or on measurement equipment, where space is limited. It belongs to the CJK Compatibility block, which includes many such precomposed units and abbreviations designed for compatibility with legacy character sets and vertical text layouts.
