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 -> mol/L via the uses solute molar mass (g/mol). Combined factor: 1 ppb = 9.99131754505e-9 mol/L. 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 conversion runs through grams per liter and uses the molar mass of Calcium Carbonate whenever a molar unit is involved.
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.)
