About Converting Fluid ounce per Seconds to Gallon per Days
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 = fluid ounce per seconds × 675
This factor comes from each unit's defined relationship to the category's base unit: 1 fluid ounce per seconds equals 0.0000295735295625 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct fluid ounce per seconds-to-gallon per days factor of 675.
Simple example
1 fl oz/s × 675 = 675 gal/d
1 fluid ounce per seconds = 675 gallon per days.
Real-world example
60 fl oz/s × 675 = 40,500 gal/d
60 fluid ounce per seconds = 40,500 gallon per days.

Frequently asked questions
How many gallon per days are in 1 fluid ounce per seconds?
1 fluid ounce per seconds equals 675 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert fluid ounce per seconds to gallon per days?
Multiply the fluid ounce per seconds value by 675. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to fluid ounce per seconds?
Use the reverse factor: 1 gallon per days equals 0.0014814815 fluid ounce per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a fluid ounce per seconds?
Fluid ounce per Seconds (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 fluid ounce per seconds to gallon per days conversion exact?
Yes. Both fluid ounce per seconds and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 675 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.
