Microsiemens (µS)
The microsiemens (µS) equals 10⁻⁶ siemens — the common unit on water-quality and conductivity (EC) meters.
Microsiemens measure dissolved-ion conductivity in aquariums, hydroponics, boiler water, and environmental monitoring.

Short background on the units used in this conversion.
The microsiemens (µS) equals 10⁻⁶ siemens — the common unit on water-quality and conductivity (EC) meters.
Microsiemens measure dissolved-ion conductivity in aquariums, hydroponics, boiler water, and environmental monitoring.
The siemens (S) is the SI unit of electrical conductance — one ampere per volt (A/V), the reciprocal of the ohm. Siemens equals mho.
Siemens quantify how easily current flows — the inverse of resistance in circuit analysis and EC/water-quality meters.
S = µS × 0.000001µS = S × 1,000,000, using the same exact factors as this converter.
