Convert Nanosiemens to Absiemens
Convert Nanosiemens (nS) to Absiemens (abS) instantly and accurately.
Conversion Formula
abS = nS × 1.000000000e-18
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.
About Absiemens
The absiemens (abS) is the conductance unit of the CGS-EMU system, equal to 1/abΩ = 1/(10⁻⁹ Ω) = 10⁹ S, exactly identical to 1 GS in SI. It appears in nineteenth- and early-twentieth-century electromagnetic engineering texts; 1 abS corresponds to the conductance of a 1 nΩ connection typical of large cryogenically cooled bus joints or welded thick-copper structures. 1 abS = 10⁹ S = 1 GS.
