Full API documentation

Explanation

For Potassium Phosphate Monobasic, g/L is the base reference and molar mass is 136.086 g/mol. ppb -> g/L via the dilute aqueous approximation: 1 ppb ~= 1 ug/l. g/L -> % w/v via the definition: 1% w/v = 1 g per 100 ml = 10 g/l. Combined factor: 1 ppb = 1e-7 % w/v. Potassium Phosphate Monobasic keeps one fixed solution-concentration basis, so the snapshot, calculator, common values, and mirror route stay aligned.

Phosphate buffer component. 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: Potassium Phosphate Monobasic. 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.)
