*For
Ohm (unit) ohm —
SI unit of electrical resistance; formerly also used upside down (℧) to represent
mho, the old name for the inverse of an ohm (now
siemens (unit) siemens with symbol S) used for electrical conductance. Note that
Unicode has separate code points for the
Ohm (unit) ohm sign (U+2126, Ω) and the Greek uppercase
omega (U+03A9, Ω).
*In
