About These Units
- Millisiemens (mS)
- Exactly 0.001 S, the conductance of a 1,000 Ω resistor. Water quality meters report conductivity in mS/cm or μS/cm, and electronics engineers use it for transistor transconductance.
- Siemens (S)
- The SI derived unit of electrical conductance, the reciprocal of the ohm, so a 2 Ω resistor has a conductance of 0.5 S. Named after Werner von Siemens, it replaced the older unit called the mho.
