About this conversion
This page converts us gallons per day (gal/d) into us fluid ounces per second (fl oz/s), two units of volumetric flow rate.
The US Gallon (gal) is a unit of volume. The Day (d) is a unit of time.
The US Fluid Ounce (fl oz) is a unit of volume. The Second (s) is a unit of time.
The formula is fl oz/s = gal/d × 0.00148148, 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.
