About Converting Fluid ounce per Seconds to Cup per Seconds
Fluid ounce per Seconds and Cup 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
cup per seconds = fluid ounce per seconds × 0.125
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 cup per seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct fluid ounce per seconds-to-cup per seconds factor of 0.125.
Simple example
1 fl oz/s × 0.125 = 0.125 cup/s
1 fluid ounce per seconds = 0.125 cup per seconds.
Real-world example
60 fl oz/s × 0.125 = 7.5 cup/s
60 fluid ounce per seconds = 7.5 cup per seconds.

Frequently asked questions
How many cup per seconds are in 1 fluid ounce per seconds?
1 fluid ounce per seconds equals 0.125 cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert fluid ounce per seconds to cup per seconds?
Multiply the fluid ounce per seconds value by 0.125. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to fluid ounce per seconds?
Use the reverse factor: 1 cup per seconds equals 8 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 cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
Is the fluid ounce per seconds to cup per seconds conversion exact?
Yes. Both fluid ounce per seconds and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.125 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.
