The original term was the Mho. Yes, Ohm spelled backwards. In nineteen
seventy one the unit was redesignated the Siemen in recognition of the work
of Ernst Werner von Siemens. I always thought spelling Ohm backwards to
indicate the reciprocal of the unit was a neat thing. No disrespect for
Ernst intended.

Siemens in the unit used to designate "Electrical Conductance."
This is the reciprocal (1/unit) of the "Ohms" unit which indicates
"Electrical Resistance."
So: siemens = 1 / ohms
micro siemens = siemens / 1,000,000
also
micro siemens = 1,000,000 / resistance
micro siemens may be written uS

I bought a COM 100 meter from silverpuppy.com. It measures the electrical
conductivity of the water, in micro Seimans. The u is a symbol for micro,
I guess it is the closest a keyboard can come to the tiny little itty
bitty m. The com 100 will tell what the conductivity is, which is pretty
close to the ppm (parts per million).
