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.
