About Converting Cup per Minutes to Cubic inch per Seconds
Cup per Minutes and Cubic inch 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
cubic inch per seconds = cup per minutes × 0.240625
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per minutes equals 0.000003943137275 base units, and 1 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct cup per minutes-to-cubic inch per seconds factor of 0.240625.
Simple example
1 cup/min × 0.240625 = 0.240625 in3/s
1 cup per minutes = 0.240625 cubic inch per seconds.
Real-world example
60 cup/min × 0.240625 = 14.4375 in3/s
60 cup per minutes = 14.4375 cubic inch per seconds.

Frequently asked questions
How many cubic inch per seconds are in 1 cup per minutes?
1 cup per minutes equals 0.240625 cubic inch per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per minutes to cubic inch per seconds?
Multiply the cup per minutes value by 0.240625. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to cup per minutes?
Use the reverse factor: 1 cubic inch per seconds equals 4.155844156 cup per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per minutes?
Cup per Minutes (cup/min) is a unit of flow rate.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the cup per minutes to cubic inch per seconds conversion exact?
Yes. Both cup per minutes and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.240625 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.
