About Converting Cubic inch per Seconds to Fluid ounce per Seconds
Cubic inch per Seconds 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 = cubic inch per seconds × 0.554112554113
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per seconds equals 0.000016387064 base units, and 1 fluid ounce per seconds equals 0.0000295735295625 base units, so dividing one by the other gives the direct cubic inch per seconds-to-fluid ounce per seconds factor of 0.554112554113.
Simple example
1 in3/s × 0.5541125541 = 0.5541125541 fl oz/s
1 cubic inch per seconds = 0.5541125541 fluid ounce per seconds.
Real-world example
60 in3/s × 0.5541125541 = 33.24675325 fl oz/s
60 cubic inch per seconds = 33.24675325 fluid ounce per seconds.

How do I convert fluid ounce per seconds back to cubic inch per seconds?
Use the reverse factor: 1 fluid ounce per seconds equals 1.8046875 cubic inch per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) 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 cubic inch per seconds to fluid ounce per seconds conversion exact?
Yes. Both cubic inch per seconds and fluid ounce per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.5541125541 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.
