So if you have a mixture of 132 mg/L, then it’s 132 PPM, and you can even perform simple conversions from things like g/L to PPM by using this fact (just convert the mass to mg and you’re done). General Formula for PPM. In general, though, you can always calculate PPM using one approach and a …

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. How to Convert Milligram/liter to Part/million (ppm) 1 mg/L = 1.001142303 part/million ppm↔ul/m3 1 ppm = 1000 ul/m3. ppm↔ug/mg 1 ug/mg = 1000 ppm. ppm↔g/ton 1 ppm = 1 g/ton.
Convert 78.0 ppm of Ca ions to mol/L. Solution: 1) By the last definition of ppm just above: 78.0 ppm …

The concentration C in parts-per million (ppm) is equal to the concentration C in milligrams per kilogram (mg/kg) and equal to 1000 times the concentration C in milligrams per liter (mg/L), divided by the solution density ρ in kilograms per cubic meter (kg/m 3): C(ppm) = C(mg/kg) = 1000 × C(mg/L) / ρ (kg/m3)

Mg/l and PPM are units used to represent the concentration. Mg/l can be abbreviated as milligrams/liter and PPM can be abbreviated as Parts per million. Mg/l can be converted to PPM with the use of specific gravity. Use this online converter for Milligrams Per Liter to Parts Per million conversion.
