The siemens (symbol: S) is an SI derived unit of measurement for electric conductance, being the inverse of the ohm (Ω), named after Werner von Siemens.
S = A / V
Mho is a now eccentric name for this unit of electrical conductance, equal to 1 Ω-1. It is derived by spelling ohm backwards. Its symbol is (the upside-down letter Ω). The term siemens is used universally in science and primarily in electrical applications, while mho is used primarily in electronic applications.
