(1) Skin conductance is usually measured in ‘Siemens’ units although sometimes ‘ mho ’ is used.(2) The maximal resolution of the system was .0488 [micro] mho .(3) An older name for the siemens is the mho , which, of course, is ohm spelled backwards (which was written as an inverted Greek omega).(4) According to the current national standard in the United States, the mho is not to be used.(5) I searched the site and could not find the conversion between reciprocal ohms or mhos and siemens.
