About this conversion
This page converts imperial gallons per day (imp gal/d) into cubic inches per second (in3/s), two units of volumetric flow rate.
The Imperial Gallon (imp gal) is a unit of volume. The Day (d) is a unit of time.
The Cubic Inch (in3) is a unit of volume. The Second (s) is a unit of time.
The formula is in3/s = imp gal/d × 0.00321087, based on the fixed relationship between these two flow rate units.
Flow rate is calculated as a volume unit divided by a time unit, so every combination of a volume unit and a time unit forms a valid, exact flow rate unit.
