Convert PPM to MG/M 3 Formula: concentration (mg/m 3 ) = 0.0409 x concentration (ppm) x molecular weight For example: 100 ppm of NH 3 (17.03 g/mol)

This tool converts volume concentration of given gas into mass (weight) concentration. Coefficients that allow to convert gas concentration expressed in ppm to ...

Converting from one unit of concentration to another ; ppm=%×10000 → 1ppm=0.0001% · %=ppm×1/10000 → 1%=10000ppm · mg/m3=ppm× M22.4×273(273+T)×P1013 · ppm=mg/m3×22.4 ...

This converter calculates the measured value in units of [ppm] into units of [mg/m3] and visa versa. The unit ppm is used in several branches in different ways.

ppm (parts per million) <-> mg/m3 (miligram per cubic meter) ... H2S is 2x1.008 + 32.06 = 34.08. Disclaimer: This Calculator is provided as a ...

To convert H2S concentration from one set of units to another simply put the known concentration in the yellow cell of the column that corresponds to the units ...

To convert units based on 25°C and 1 atm, fill in the ppm value (or the mg/m3 value) and the molecular mass, and click “Calculate”.

20 авг. 2021 г. · Thus, mg/m3 represents milligrams (one-thousandth of a gram) per cubic metre of air, while µg/m3 stands for micrograms (one-millionth of a gram) ...

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.
