Set Base Gas Standard Volume Unit to SCF.
Set Base Time Unit to minutes (min).
Calculate the conversion factor:
a. 1 thousands of standard cubic feet per minute = 1000 cubic feet per minute
b. Gas Standard Volume Flow Conversion Factor = 1 ÷ 1000 = 0.001 standard
Set Gas Standard Volume Flow Conversion Factor to 0.001.
Set Gas Standard Volume Flow Label to MSCFM.
Set Gas Standard Volume Total Label to MSCF.
