This category of measurement units is defined by the "electric conductance" type, which is an SI derived quantity.
The SI derived unit for electric conductance is the siemens.
The siemens is the SI derived unit of electric conductance. It is equal to inverse ohm. It is named after the German inventor and industrialist Ernst Werner von Siemens, and was previously called the mho. In English, the term siemens is used both for the singular and plural. The 14th General Conference on Weights and Measures approved the addition of the siemens as an SI derived unit in 1971.
