About Converting Cubic inch per Seconds to Cup per Minutes
Cubic inch 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. Both are volumetric flow rate units.
Formula
cup per minutes = cubic inch per seconds × 4.15584415584
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 cup per minutes equals 0.000003943137275 base units, so dividing one by the other gives the direct cubic inch per seconds-to-cup per minutes factor of 4.15584415584.
Simple example
1 in3/s × 4.155844156 = 4.155844156 cup/min
1 cubic inch per seconds = 4.155844156 cup per minutes.
Real-world example
60 in3/s × 4.155844156 = 249.3506494 cup/min
60 cubic inch per seconds = 249.3506494 cup per minutes.

How do I convert cup per minutes back to cubic inch per seconds?
Use the reverse factor: 1 cup per minutes equals 0.240625 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 cup per minutes?
Cup per Minutes (cup/min) is a unit of flow rate.
Is the cubic inch per seconds to cup per minutes conversion exact?
Yes. Both cubic inch per seconds and cup per minutes are defined by fixed standards rather than physical artifacts, so the factor of 4.155844156 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.
