API, OpenAPI and WebMCP documentation

Explanation

ppb = mol/L × 248180000.

Molar mass: 248.18 g/mol for Sodium Thiosulfate Pentahydrate. Dechlorination reagent reference. A different hydrate or chemical form requires its own molar mass.

Approximation: mass-fraction ppm ≈ mg/L and ppb ≈ µg/L only for dilute aqueous solutions near 1 kg/L. This converter has no measured solution-density input.

Method & Solute Basis

  • Method basis: this conversion runs through grams per liter and uses the molar mass of Sodium Thiosulfate Pentahydrate whenever a molar unit is involved.
  • Solute reference: Sodium Thiosulfate Pentahydrate. The page keeps one fixed g/L normalization path for this solute.
  • Consistency rule: calculator output and table values use the same constants and rounding policy.
  • Source: Solution concentration reference model (Stated molar mass: 248.18 g/mol for Sodium Thiosulfate Pentahydrate. Dilute aqueous approximation, density near 1 kg/L.)
