Unicode Version 17.0
㍖
U+3356 "㍖" Square Rentogen is a CJK compatibility ideograph that represents the Japanese unit of measurement for electrical resistance, the ohm, using the kanji characters for "rentogen" which is derived from the German physicist Wilhelm Röntgen's name, though it is important to note that the ohm is actually named after Georg Ohm, so this square form encodes a historical or alternative naming convention for the unit, and it is part of a set of squared katakana and kanji abbreviations used in East Asian text for compact notation in technical or specialized contexts.
