ppm is the volume concentration. Conversion relationship of gas detection concentration unit: ppm and milligrams / cubic meter There are two ways to represent pollutant concentrations in ambient air (air): 2005-06-24 Concentration of Solution: Parts per million (ppm) 1. If playback doesn't begin shortly, try restarting your device. Videos you watch may be added to the TV's watch history and influence TV In water solution, the concentration C in parts-per million (ppm) is equal to the concentration C in milligrams per kilogram (mg/kg) and equal to 1000000 times the molar concentration (molarity) c in moles per liter (mol/L), times the solute molar mass in grams per mole (g/mol), divided by the water solution density at temperature of 20ºC 998.2071 in kilograms per cubic meter (kg/m 3): PPM, or parts-per-million, is a way of expressing very dilute concentrations of substances. Usually describes the concentration of something in water or soil.

On utilise surtout le ppm pour exprimer une fraction massique (1 ppm = 1 mg/kg) [b]. Saline water (more commonly known as salt water) is water that contains a high concentration of dissolved salts (mainly sodium chloride).The salt concentration is usually expressed in parts per thousand (permille, ‰) or parts per million (ppm). ppm is the volume concentration.
