About Converting Fluid ounce per Seconds to Cup per Hours
Fluid ounce per Seconds and Cup per Hours 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 hours = fluid ounce per seconds × 450
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 hours equals 6.571895e-8 base units, so dividing one by the other gives the direct fluid ounce per seconds-to-cup per hours factor of 450.
Simple example
1 fl oz/s × 450 = 450 cup/h
1 fluid ounce per seconds = 450 cup per hours.
Real-world example
60 fl oz/s × 450 = 27,000 cup/h
60 fluid ounce per seconds = 27,000 cup per hours.

Frequently asked questions
How many cup per hours are in 1 fluid ounce per seconds?
1 fluid ounce per seconds equals 450 cup per hours, using the exact defined conversion factor rather than an estimate.
How do I convert fluid ounce per seconds to cup per hours?
Multiply the fluid ounce per seconds value by 450. The converter above does this instantly to whatever precision you set.
How do I convert cup per hours back to fluid ounce per seconds?
Use the reverse factor: 1 cup per hours equals 0.0022222222 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 hours?
Cup per Hours (cup/h) is a unit of flow rate.
Is the fluid ounce per seconds to cup per hours conversion exact?
Yes. Both fluid ounce per seconds and cup per hours are defined by fixed standards rather than physical artifacts, so the factor of 450 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.
