• 3So, to convert from µg/m to ppmV, we plug in our mass values in equation 2 above, making sure to convert our µg to units of grams required by the equation. This will give us the volume of our contaminant in liters. We must now convert this into mL for equation 3. Then we simply divide by the sample volume in m3 to obtain our result in ppmV.
