Electrical conductanceexact by definition
The siemens is the SI unit of electrical conductance, the reciprocal of the ohm. One siemens is one ampere per volt, so a one ohm resistor has a conductance of one siemens. The relation is exact by definition, the siemens being a coherent derived SI unit.

Where the unit came from
Named for Werner von Siemens. The unit was previously called the mho, which is ohm spelled backwards, and older instruments and textbooks still use that name with the symbol of an upside-down omega.
