About Converting Imperial fluid ounce per Seconds to Gallon per Days
Imperial fluid ounce per Seconds and Gallon per Days both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
gallon per days = imperial fluid ounce per seconds × 648.512959773
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial fluid ounce per seconds equals 0.0000284130625 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct imperial fluid ounce per seconds-to-gallon per days factor of 648.512959773.
Simple example
1 imp fl oz/s × 648.5129598 = 648.5129598 gal/d
1 imperial fluid ounce per seconds = 648.5129598 gallon per days.
Real-world example
60 imp fl oz/s × 648.5129598 = 38,910.77759 gal/d
60 imperial fluid ounce per seconds = 38,910.77759 gallon per days.

What is a imperial fluid ounce per seconds?
Imperial fluid ounce per Seconds (imp fl oz/s) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the imperial fluid ounce per seconds to gallon per days conversion exact?
Yes. Both imperial fluid ounce per seconds and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 648.5129598 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
