Convert mgl to ppm

Answer 1

1 mg/L = 1 ppm

Assumption: 1 cm3 of pure water = 1g =1000mg

1 litre water = 1000 ml = 1000 g = 1 000 000 μl or 1 000 000 mg

1 mg/1 litre = 1 mg/ 1 000 000 μl = 1mg/1 000 000 mg = 1 ppm

Note:

mg/L is most frequently used in measurements of material in water or other liquids. ppm is used as a measure of gases in other gases and is based on volume or mole ratios not weight or mass. As a clarification ppm is usually written as ppmv (parts per million volume)
