SwitchExplanation
Formula: Percent Weight/Volume = Parts per Million × 0.0001. Why: the route normalizes through g/L, with ppm treated as approximately mg/L and ppb treated as approximately ug/L under the dilute aqueous assumption used by this family.
Parts per Million (ppm): a reporting unit treated here as approximately equal to mg/L under dilute aqueous assumptions.
Percent Weight/Volume (% w/v): a formulation unit defined as grams of solute per 100 mL of solution, equivalent to 10 g/L for each 1% w/v.
This route is useful when comparing formulation-style concentration for Sodium Hydroxide with dilute-solution reporting units used in process, water-treatment, or dosing references.
This conversion is multiplicative within one fixed solution model because both units are normalized through g/L, with solute-specific molar-mass constants applied only where molar units are involved.
