Pump Flow Metric Conversion Factors

Use these factors to convert from English to metric

Data Input

For Pump depth and Header back pressure, multiply meters by a factor of 3.33 to input data in units of feet.

Flow Rate

Multiply U.S. gallons by 3.79 to convert to liters.

Air Consumption

Multiply SCFM by 0.029 to express in cubic meters.

Data Input (feet)

Enter pump depth in well
Header back pressure
Total developed head

Flow Rate (gpm)

Maximum
Enter desired flow rate
Default is maximum flow rate

Air consumption per pump
scfm delivered at 100 psi
Number of pumps driven by compressor
