This calculator allows you to convert between parts per million (ppm), milligrams per liter (mg/L) and the molar concentration (M).
Parts per million (ppm) is a measure of how many parts of a substance are in a million parts of the mixture.
Milligrams per liter (mg/L) is a measure of the concentration, it is how many milligrams of a substance are in a liter of the mixture.
Molarity (M) expresses the number of moles in a liter of a substance and is described in M or mol/L.
