Understanding the Units

What is a Microsiemen?

The siemens is the SI derived unit of electrical conductance, equal to the reciprocal of the ohm (1 S = 1 A/V = 1/Ω).

Named after Werner von Siemens (1816–1892), German industrialist and inventor.

Common contexts: conductivity measurement, electrical engineering.
