The parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. To convert from molarity to ppm, first determine the molar mass of a substance. For instance, chloride has a molar mass of 35.5. A solution with 1 M concentration would have 35.5 g of chloride per 1 L of solution. Molecular weight of substance = 28 Molar volume = 22.4 litres (In this example the molecule is CO) 2.1 To convert concentrations in ppm to mg/m3 Concentration of substance = 120 ppm Molecular weight of substance = 28 Molar volume = 22.4 litres Concentration in mg/m3 = concentration (ppm) x molecular weight of substance molar volume = 120 ppm x 28 parts per million is abbreviated as ppm 1 ppm is one part by weight, or volume, of solute in 1 million parts by weight, or volume, of solution.

You can perform a PPM conversion easily provided you have two quantities in the same unit (or that you can convert into the same unit) or a percentage value. PPM means "parts per million," so to calculate it you divide the amount of the solute by the total amount of solution, them multiply by 10^6.

Parts per million: PPM is expressed as milligrams per liter(mg/L). It measures the mass of the chemical substance or concentration per unit weight of water/solid or volume of one part of gas. One part per million is equal to 0.000001 units. Molarity: It is the number of moles of a solute per liter of solution. It express the concentration of a

PPM is used in the measurement of a small level of pollutants such as air, water, body fluids, etc. Use Percent to PPM conversion calculator to convert values from molecular weight percent to parts per million. In the input field of Molecular Weight you could either choose from the drop-down list, or you ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000.
