SwitchExplanation
Formula: Millimoles per Liter = Parts per Million × 0.002921. Why: the route normalizes through g/L and uses the solute molar mass for Lactose (M = 342.296 g/mol) whenever molar concentration units are part of the conversion.
Parts per Million (ppm): a reporting unit treated here as approximately equal to mg/L under dilute aqueous assumptions.
Millimoles per Liter (mmol/L): a smaller molar concentration unit equal to one thousandth of a mole per liter and still dependent on the molar mass of Lactose when mass-based units are involved.
This route is useful when translating the concentration of Lactose between chemistry-oriented molar notation and mass-based or formulation-style reporting units.
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.
