Full API documentation

Explanation

For Phosphoric Acid, g/L is the base reference and molar mass is 97.994 g/mol. % w/v -> g/L via the definition: 1% w/v = 1 g per 100 ml = 10 g/l. g/L -> mmol/L via the uses solute molar mass with si milli scaling. Combined factor: 1 % w/v = 102.047064106 mmol/L. Phosphoric Acid keeps one fixed solution-concentration basis, so the snapshot, calculator, common values, and mirror route stay aligned.

Triprotic acid reference. 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 Phosphoric Acid whenever a molar unit is involved.
Solute reference: Phosphoric Acid. 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.)
