For these conditions, the equation to convert from concentration in parts per million (ppm) to concentration in milligrams per cubic meter (mg/m3) is as follows: Concentration (mg/m3) = 0.0409 x concentration (ppm) x. molecular weight. For automatic calculation, you can use NIOSH calculator – Click here to use.

PPM, which could be either PPM (wt) or PPM (vol), or g/m3, which does not specify whether the gas is at actual or standard condition (which makes a big difference in case of sales gas). Originally, I was told that: ppm (wt) x 1000x Density = mg/m3, and ppm (vol)x1000 = mg/m3

1 000 ppm = 1 ‰ 10 000 ppm = 1 %. Ympäristömyrkkyjen ohjearvot, kuten suurin sallittu pitoisuus maaperässä, hengitysilmassa, juomavedessä tai ravinnossa, ilmoitetaan usein ppm:inä. C(ppm) = C(mg/kg) = 10 6 × c(mol/L) × M(g/mol) / ρ (kg/m3) 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 Percent to ppm converter How to convert ppm to percent.

Solution: In water, ppm is 10 Jul 2019 TVOC can be measured in micrograms per cubic meter (µg/m3) of air, milligrams per cubic meter (mg/m3), parts per million (ppm) or parts per In solutions, ppm refers to mg/liter or grams/m3. Note that it represents a ratio of mass to volume. This can be done because the mass of water is the same as its part of a specific unit and in our case a gram.
