PPM to mg/L

The relation between PPM (Parts per Million) and mg/L is dependent on the solute density. Enter the ppm and the solute desity values to find the mg/L ratio.

If you already know the mg/L ratio of your solution, you can also use this PPM to mg/L converter to calculate the molarity This parameter describes the number of moles in a liter of the solution and is expressed in molars (1 M = mol/L).
