About Converting Cubic inch per Hours to Quart per Minutes
Cubic inch per Hours and Quart 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
quart per minutes = cubic inch per hours × 0.0002886002886
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per hours equals 4.551962e-9 base units, and 1 quart per minutes equals 0.0000157725491 base units, so dividing one by the other gives the direct cubic inch per hours-to-quart per minutes factor of 0.0002886002886.
Simple example
1 in3/h × 0.0002886002886 = 0.0002886003 qt/min
1 cubic inch per hours = 0.0002886003 quart per minutes.
Real-world example
60 in3/h × 0.0002886002886 = 0.0173160173 qt/min
60 cubic inch per hours = 0.0173160173 quart per minutes.

How do I convert quart per minutes back to cubic inch per hours?
Use the reverse factor: 1 quart per minutes equals 3,465 cubic inch per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per hours?
Cubic inch per Hours (in3/h) is a unit of flow rate.
What is a quart per minutes?
Quart per Minutes (qt/min) is a unit of flow rate.
Is the cubic inch per hours to quart per minutes conversion exact?
Yes. Both cubic inch per hours and quart per minutes 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.
