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. 


Gram/Litre

The gram per litre (g/L) is a common unit of mass concentration used in chemistry, medicine, and environmental science. Blood protein concentrations, saline solutions, and pollutant levels in water are frequently expressed in g/L.
