Milligram per Liter to PPM Converter

Convert milligrams per liter (mg/L) to parts per million (ppm) instantly. Essential for water quality testing and chemical analysis.

mg/L

Parts Per Million (ppm)

1 mg/L = 1 ppm (for water)

About mg/L

Milligrams per liter (mg/L) is a unit of concentration expressing the mass of a substance dissolved in a given volume of solution. Commonly used in water quality analysis.

1 mg/L = 1 milligram per 1000 mL

About PPM

Parts per million (ppm) is a dimensionless unit expressing the ratio of one part substance to one million parts of the solution. For water solutions, 1 mg/L equals 1 ppm.

1 ppm = 1 part in 1,000,000 parts
