U+2127 "℧" Inverted Ohm Sign Unicode Character
Unicode Version 17.0
℧
U+2127 "℧" Inverted Ohm Sign is a typographical symbol representing the reciprocal of the ohm, the standard unit of electrical resistance, and thus denotes the unit of electrical conductance known as the siemens or, historically, the mho. Its distinctive upside-down capital omega glyph visually echoes the ohm symbol (Ω) while indicating the inverse relationship, with "mho" itself being "ohm" spelled backwards. Although largely replaced by the siemens (S) in modern scientific use, the inverted ohm sign persists in some mathematical notations and legacy electrical engineering contexts as a clear graphical shorthand for conductance.
