The statmho is the unit of electrical conductance in the electrostatic system of units (ESU), an extension of the centimeter-gram-second (CGS) system to cover electrical units.
It is sometimes called the statsiemens, with symbol statS.
[1] In the ESU system, the permittivity of free space is set to unity by definition.
In the case of the statmho, the conversion from siemens (S) is given by:[2] The value of c in the SI system is 299792458 metres per second exactly by definition.
However, in the era in which the ESU system was in use, the speed of light was determined by measurement and was taken to be approximately 29973000000 centimetres per second.
