1 h (Hour) = 60 min (Minutes)
Then: 1 scf/h = × = 0.016667 StdCuft/min
1 scf/h = 0.016667 StdCuft/min
Therefore:
Base per Custom = = = 0.016667

To find the Base per Custom relationship for a custom unit of standard millions of standard
cubic feet per day (mmcfd) and a base unit of standard cubic feet per minute (StdCuft/
min), input the following:
Custom Unit = mmcfd Base Unit = StdCuft/min
Because:
1 mmcf (Millions of Standard Cubic Feet) = 1000000 StdCuft (Standard Cubic Feet) and
1 d (Day) = 1440 min (Minutes)
Then:
1 mmcfd = × × = 694.444 StdCuft/min
1 mmcfd = 694.444 StdCuft/min
Therefore:
Base per Custom = = = 694.444
