TDS ↔ EC converter

Conductivity (µS/cm) and total dissolved solids (mg/L) translate through a factor that depends on the dominant salt mix.

TDS
512mg/L
= 0.512 g/L
Within the SANS 241 ideal aesthetic range (≤ 600 mg/L).
EC
800µS/cm
= 0.8 mS/cm
Resistivity
1.25kΩ·cm
Water quality reading
Conductivity of 800 µS/cm at factor 0.64 corresponds to 512 mg/L TDS and a resistivity of 1.25 kΩ·cm.
Within the SANS 241 ideal aesthetic range (≤ 600 mg/L).
