About Converting Cubic foot per Seconds to Cup per Minutes
Cubic foot per Seconds and Cup per Minutes 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. Cubic foot per Seconds is most often used for the standard unit used by the us geological survey for reporting river and stream discharge at gauging stations.
Formula
cup per minutes = cubic foot per seconds × 7181.2987013
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per seconds equals 0.028316846592 base units, and 1 cup per minutes equals 0.000003943137275 base units, so dividing one by the other gives the direct cubic foot per seconds-to-cup per minutes factor of 7181.2987013.
Simple example
1 ft3/s × 7181.298701 = 7,181.298701 cup/min
1 cubic foot per seconds = 7,181.298701 cup per minutes.
Real-world example
60 ft3/s × 7181.298701 = 430,877.9221 cup/min
60 cubic foot per seconds = 430,877.9221 cup per minutes.

What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
What is a cup per minutes?
Cup per Minutes (cup/min) is a unit of flow rate.
Is the cubic foot per seconds to cup per minutes conversion exact?
Yes. Both cubic foot per seconds and cup per minutes are defined by fixed standards rather than physical artifacts, so the factor of 7181.298701 used above is exact to as many digits as you choose to display.
Where is the cubic foot per seconds still used today?
United States
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.
