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
PPM(Parts Per Million) To Mg/M3.
ppm in NTP = (ppm * molecular weight) / 24.45
exp: (55.6 * 30.6) / 24.5 = 69.58 MgM3
ppm in STP = (ppm * Molecular Weight) / 22.45
exp: (55.6 * 30.6) / 22.5 = 75.61 MgM3
