Parts Per Billion To Mg/M3 Conversion
STP (Standard Temperature and Pressure): defined at air 1 atm or 1 atmosphere at 00C - 273.15 K, 320F. - In STP (1 Mole) of a Gas is equal to 22.45 Litres
NTP (Normal Temperature and Pressure): defined at air 1 atm or 1 atmosphere at 200C - 293.15 K, 680F. - In NTP (1 Mole) of a Gas is equal to 24.45 Litres
PPB(Parts Per Billion) To Mg/M3.
ppb in STP = ((ppb / 1000) * Molecular Weight) / 22.45
exp: ((55.6 / 1000) * 30.6) / 22.5 = 0.07 MgM3
