TDS Calculator

Convert Electrical Conductivity (EC) to Total Dissolved Solids (TDS)

Formula: TDS (mg/L) = EC (μS/cm) × Conversion Factor
Estimates dissolved mineral content based on electrical conductivity measurements.

Calculation Results

⚠️ TDS meters do not measure dissolved solids directly; they calculate TDS by measuring electrical conductivity (EC) and applying an assumed conversion factor. Non-conductive organic compounds (like sugars or oils) and temperature variations can alter accuracy.
