Total Dissolved Solids (TDS) represents the combined content of all inorganic and organic substances dissolved in water — including minerals, salts, metals, and organic matter. TDS is a key indicator of drinking water quality and is easily estimated from electrical conductivity measurements.
The WHO recommends drinking water TDS below 600 mg/L for palatability, though up to 1,000 mg/L is considered acceptable. TDS above 1,200 mg/L may cause scaling in pipes and poor taste. This calculator converts conductivity readings to TDS using the standard conversion factor.
TDS = electrical conductivity × conversion factor. The factor ranges 0.5–0.8 depending on water composition; 0.65 is the standard default. Classes: 1 (<300 mg/L): Excellent, 2 (300–600): Good, 3 (600–1000): Fair, 4 (>1000): Poor.
TDS below 300 mg/L is excellent drinking water. Most bottled water is 100–300 mg/L. Municipal supplies are typically 200–500 mg/L. Reverse osmosis systems reduce TDS by 90–99%.

Total Dissolved Solids is a quantitative measure used in environmental science and ecology. It represents key metrics that help researchers, policymakers, and individuals understand environmental impacts. The specific definition and measurement methodology are established by international scientific organizations and regulatory bodies.
How is TDS measured involves analyzing relevant parameters using established scientific methodologies. Our calculator applies peer-reviewed formulas and standard emission factors to provide accurate results. The specific approach varies by parameter but follows guidelines from organizations such as the EPA, IPCC, and relevant scientific bodies.
