Conversion Factors B-5
Conversion Table
The relationship between water vapor concentration and other conversion factors to express the con-
centration of water vapor in a gas is:
Parts per Million by Volume x Factor = Conversion
Parts per Million by Volume x 8.04 x 10
-4
= mg/L
18
Parts per Million by Volume x ————— = Parts per Million by Weight
*M Wt
Parts per Million by Volume x 4.76 x 10
–2
= lb/mmft
3
___________
*M Wt = Molecular weight of sample gas
