About Converting Fluid ounce per Days to Gallon per Seconds
Fluid ounce per Days and Gallon per Seconds 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 seconds = fluid ounce per days × 9.042245e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 fluid ounce per days equals 3.422862e-10 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct fluid ounce per days-to-gallon per seconds factor of 9.042245e-8.
Simple example
1 fl oz/d × 9.042245e-8 = 9.042245e-8 gal/s
1 fluid ounce per days = 9.042245e-8 gallon per seconds.
Real-world example
60 fl oz/d × 9.042245e-8 = 0.0000054253 gal/s
60 fluid ounce per days = 0.0000054253 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 fluid ounce per days?
1 fluid ounce per days equals 9.042245e-8 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert fluid ounce per days to gallon per seconds?
Multiply the fluid ounce per days value by 9.042245e-8. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to fluid ounce per days?
Use the reverse factor: 1 gallon per seconds equals 11,059,200 fluid ounce per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a fluid ounce per days?
Fluid ounce per Days (fl oz/d) is a unit of flow rate.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the fluid ounce per days to gallon per seconds conversion exact?
Yes. Both fluid ounce per days and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 9.042245e-8 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.
