竖翻欧姆标记 ℧

Inverted Ohm Sign is commonly used to denote electrical conductivity. The logic behind this symbol is simple: since we measure resistance in Ohms, the inverse quantity (conductivity) will receive the opposite name — 「Mho」 and an inverted symbol.

Despite its simplicity, this naming convention has not been adopted worldwide. In the SI system, electrical conductivity is denoted by the uppercase Latin letter 「S」. It is, of course, also included in Unicode: S . Use both options in your calculations and scientific work.

符号 「竖翻欧姆标记」 包含在 「字母式符号」 块的 「字母符號」 子块中，并在1993年作为Unicode版本1.1的一部分获得批准。
