About Converting Cup per Seconds to Cubic foot per Minutes
Cup per Seconds and Cubic foot 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. Both are volumetric flow rate units.
Formula
cubic foot per minutes = cup per seconds × 0.501302083333
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per seconds equals 0.0002365882365 base units, and 1 cubic foot per minutes equals 0.0004719474432 base units, so dividing one by the other gives the direct cup per seconds-to-cubic foot per minutes factor of 0.501302083333.
Simple example
1 cup/s × 0.5013020833 = 0.5013020833 ft3/min
1 cup per seconds = 0.5013020833 cubic foot per minutes.
Real-world example
60 cup/s × 0.5013020833 = 30.078125 ft3/min
60 cup per seconds = 30.078125 cubic foot per minutes.

Frequently asked questions
How many cubic foot per minutes are in 1 cup per seconds?
1 cup per seconds equals 0.5013020833 cubic foot per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cup per seconds to cubic foot per minutes?
Multiply the cup per seconds value by 0.5013020833. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per minutes back to cup per seconds?
Use the reverse factor: 1 cubic foot per minutes equals 1.994805195 cup per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
What is a cubic foot per minutes?
Cubic foot per Minutes (ft3/min) measures volumetric flow rate. One cubic foot of volume passing a point every minute. It is classified as a US customary flow-rate unit.
Is the cup per seconds to cubic foot per minutes conversion exact?
Yes. Both cup per seconds and cubic foot per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.5013020833 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.
