About Converting Cubic inch per Minutes to Quart per Seconds
Cubic inch per Minutes and Quart 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
quart per seconds = cubic inch per minutes × 0.0002886002886
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per minutes equals 2.731177e-7 base units, and 1 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct cubic inch per minutes-to-quart per seconds factor of 0.0002886002886.
Simple example
1 in3/min × 0.0002886002886 = 0.0002886003 qt/s
1 cubic inch per minutes = 0.0002886003 quart per seconds.
Real-world example
60 in3/min × 0.0002886002886 = 0.0173160173 qt/s
60 cubic inch per minutes = 0.0173160173 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 cubic inch per minutes?
1 cubic inch per minutes equals 0.0002886003 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per minutes to quart per seconds?
Multiply the cubic inch per minutes value by 0.0002886002886. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to cubic inch per minutes?
Use the reverse factor: 1 quart per seconds equals 3,465 cubic inch per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per minutes?
Cubic inch per Minutes (in3/min) is a unit of flow rate.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the cubic inch per minutes to quart per seconds conversion exact?
Yes. Both cubic inch per minutes and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0002886002886 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.
