About Kilosiemens
The kilosiemens (kS) equals 10³ S, encountered in high-conductance metallic connections and power-semiconductor on-state characterisation. A large copper busbar of 100 mm² cross-section and 1 m length has conductance of about 60 kS; high-power IGBT modules with Rₛₒₙ below 1 mΩ present conductances exceeding 1 kS; arc furnace electrodes exhibit kilosiemens-range contact conductance. 1 kS = 10³ S = 10⁻³ MS.
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.
