Full API documentation

Explanation

For Calcium Carbonate, g/L is the base reference and molar mass is 100.0869 g/mol. ppb -> g/L via the dilute aqueous approximation: 1 ppb ~= 1 ug/l. g/L -> ppm via the dilute aqueous approximation: 1 ppm ~= 1 mg/l. Combined factor: 1 ppb = 0.001 ppm. Calcium Carbonate keeps one fixed solution-concentration basis, so the snapshot, calculator, common values, and mirror route stay aligned.

Common carbonate mineral and reagent. When molar units are involved, the same molar-mass assumption stays constant rather than switching reference values between blocks.

Method & Solute Basis

Method basis: this page converts through grams per liter, with ppm treated as approximately mg/L and ppb treated as approximately ug/L under the dilute aqueous assumption used in this family.
Solute reference: Calcium Carbonate. 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 (Fixed molar masses (g/mol), SI concentration definitions, and dilute aqueous approximations where ppm ≈ mg/L and ppb ≈ ug/L.)
