(µ𝑔)⁄𝑚^3 =concentration (𝒑𝒑𝒃)× (molecular weight of the gas (𝑔⁄𝑚𝑜𝑙))/ (standard molar volume of ideal gas (𝐿)) 𝑚𝑔⁄𝑚^3 =concentration (𝒑𝒑𝒎)× (molecular weight of the gas For acetone, 1000 ppm is approx. 2400 mg/m³, so 10 mg/m³ x (1000 ppm / 2400 mg/m³ = 4.17 NOTE: For gases the ppm is exact, mg/m³ is rounded Hard way Molar mass of acetione 58.08 g/mol Molar volume of ideal gas at 1 atm, 25 °C (OSHA and EPA standard conditions): 24.467 L or 0.024467 m³ I have come across this formula : Concentration (ppm) = 24.45 x concentration (mg/m3) ÷ molecular weight How do you calculate the molecular weight of PM 2.5? Thanks for your reply Using Arduino How to convert Milligrams Per Cubic Meter to Parts Per Million (mg/m3 to ppm)? 1 mg/m3 = 0.001 ppm. 1 x 0.001 ppm = 0.001 Parts Per Million. Always check the results; rounding errors may occur. Definition: In relation to the base unit of [density] => (kilograms per cubic meter), 1 Milligrams Per Cubic Meter (mg/m3) is equal to 1.0E-6 kilograms How to convert Parts Per Million to Milligrams Per Milliliter (ppm to mg/ml)?

Cubic centimeter (centimetre) is a metric system volume unit. 1 cm3 = 0.000001 m3. The symbol is " cm³ ". Please visit all volume units conversion to convert all volume units. This on the web one-way conversion tool converts density units from milligrams per liter ( mg/l ) into grams per cubic meter ( g/m3 ) instantly online. 1 milligram per liter ( mg/l ) = 1.00 grams per cubic meter ( g/m3 ). In the video I show you the "full solution" way if  ppm↔mg/m3 1 ppm = 1000 mg/m3; ppm↔g/cm3 1 g/cm3 = 1000000 ppm; ppm ↔mg/L 1 ppm = 1  This PPM to mg/m3 conversion is based on the molecular weight of the chemical and it is different for every chemical. Fill in either the “ppm” value (X) or the “mg/m3” value (Y) AND the molecular weight of the compound. Then press the “Calculate” button. ppm (parts per million), This unit that expresses concentration in parts per mg/ m3 (milligram per cubic metre), This unit expresses the concentration in one  For that purpose when I mix each 50 mL volume of 50 mg/L concentration of individual heavy metals in a solution, the How to convert mg/L (ppm) to mg/kg? CONVERT PPM TO MG/M 3. Formula: concentration (mg/m3) = 0.0409 x concentration (ppm) x molecular weight. For example: 100 ppm of NH 3 (17.03 g/mol) 0.0409 x 100 ppm x 17.03 = 69.652.
