About Converting Gallon per Days to Fluid ounce per Seconds
Gallon per Days and Fluid ounce 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
fluid ounce per seconds = gallon per days × 0.00148148148148
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 fluid ounce per seconds equals 0.0000295735295625 base units, so dividing one by the other gives the direct gallon per days-to-fluid ounce per seconds factor of 0.00148148148148.
Simple example
1 gal/d × 0.001481481481 = 0.0014814815 fl oz/s
1 gallon per days = 0.0014814815 fluid ounce per seconds.
Real-world example
60 gal/d × 0.001481481481 = 0.0888888889 fl oz/s
60 gallon per days = 0.0888888889 fluid ounce per seconds.

Frequently asked questions
How many fluid ounce per seconds are in 1 gallon per days?
1 gallon per days equals 0.0014814815 fluid ounce per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to fluid ounce per seconds?
Multiply the gallon per days value by 0.001481481481. The converter above does this instantly to whatever precision you set.
How do I convert fluid ounce per seconds back to gallon per days?
Use the reverse factor: 1 fluid ounce per seconds equals 675 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a fluid ounce per seconds?
Fluid ounce per Seconds (fl oz/s) is a unit of flow rate.
Is the gallon per days to fluid ounce per seconds conversion exact?
Yes. Both gallon per days and fluid ounce per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.001481481481 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.
