About Siemens

The siemens (S) is the SI derived unit of electrical conductance, equal to 1 ampere per volt (1 A/V = 1 Ω⁻¹ = 1 kg⁻¹·m⁻²·A²·s³), named after Werner von Siemens (1816-1892). Also known as the mho (℧), it describes how easily current flows: a 1 Ω resistor has 1 S conductance. Power MOSFETs are characterised by 1/Rₛ_ₒₙ in siemens; large RF transistors operate with transconductance of 1-10 S.

About Nanosiemens

The nanosiemens (nS) equals 10⁻⁹ S, the scale for JFET gate leakage, ion-channel patch-clamp measurements, and high-value resistor characterisation. A 1 GΩ resistor presents 1 nS; single open ion channels in biological membranes are quantified in nanosiemens by patch-clamp electrophysiology; environmental soil conductivity sensors use nanosiemens readouts at high resistivity. 1 nS = 10⁻³ µS = 10⁻⁹ S.
