Convert Siemens (S) to Megasiemens (MS) instantly and accurately.
Conversion Formula
MS = S × 1.000000000e-6
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 Megasiemens
The megasiemens (MS) equals 10⁶ S, the scale for very-low-resistance metallic structures such as thick busbars and short heavy-gauge connectors. A 10 cm long, 1 cm² copper bar has conductance of roughly 600 MS; aluminium overhead grid feeders have per-span conductances in the megasiemens range; conductance of grain boundaries in polycrystalline conductors at cryogenic temperatures reaches megasiemens. 1 MS = 10⁶ S = 10³ kS.
