The siemens is the derived unit of electric conductance, electric susceptance, and electric admittance in the International System of Units.

What is the meaning of unit siemens?

Siemens (S), unit of electrical conductance. In the case of direct current (DC), the conductance in siemens is the reciprocal of the resistance in ohms (S = amperes per volts); in the case of alternating current (AC), it is the reciprocal of the impedance in ohms.

How do you write siemens units?

As with all SI units whose names are derived from the proper name of a person, the first letter of its symbol is uppercase (S). But when an SI unit is spelled out, it should always be written in lowercase (siemens), unless it begins a sentence or is the name "degree Celsius".
