PPMs are just like temperature (celcius or fahrenheit?), pressure (absolute or gauge?), and % (of what?). Upvote 0 Downvote

Mar 11, 2009 #4 Montemayor Chemical Joined Apr 6, 2001 Messages 1,436 Location US It is not possible to convert lb water/million lbs of gas to lb water/million Scf without first establishing the molecular weight of the gas in question. If you do know the dry gas's molecular weight, then the conversion can be done as follows: lb water/MM Scf = (lb water/MM lb gas)(mol. wt. of gas)/(379.5 Scf) The above Scf value of one lb-mol is measured at 70 oF and 14.696 psia - as per the NGPSA.
