Part/Million (ppm)

Parts per million (ppm) is a dimensionless unit of concentration equal to one part of a substance per million parts of the mixture by mass or volume. It is widely used for trace contaminants in water, air quality monitoring, and analytical chemistry. 1 ppm ≈ 1 mg/L in dilute aqueous solutions. 


Milligram/Litre

The milligram per litre (mg/L) is equivalent to parts per million (ppm) for dilute aqueous solutions. It is the standard unit for water quality parameters such as dissolved oxygen, hardness, and trace pollutant concentrations in drinking water standards.
