About Converting Quart per Minutes to Cubic inch per Hours
Quart per Minutes and Cubic inch per Hours 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 hours = quart per minutes × 3465
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per minutes equals 0.0000157725491 base units, and 1 cubic inch per hours equals 4.551962e-9 base units, so dividing one by the other gives the direct quart per minutes-to-cubic inch per hours factor of 3465.
Simple example
1 qt/min × 3465 = 3,465 in3/h
1 quart per minutes = 3,465 cubic inch per hours.
Real-world example
60 qt/min × 3465 = 207,900 in3/h
60 quart per minutes = 207,900 cubic inch per hours.

Frequently asked questions
How many cubic inch per hours are in 1 quart per minutes?
1 quart per minutes equals 3,465 cubic inch per hours, using the exact defined conversion factor rather than an estimate.
How do I convert quart per minutes to cubic inch per hours?
Multiply the quart per minutes value by 3465. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per hours back to quart per minutes?
Use the reverse factor: 1 cubic inch per hours equals 0.0002886003 quart per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per minutes?
Quart per Minutes (qt/min) is a unit of flow rate.
What is a cubic inch per hours?
Cubic inch per Hours (in3/h) is a unit of flow rate.
Is the quart per minutes to cubic inch per hours conversion exact?
Yes. Both quart per minutes and cubic inch per hours are defined by fixed standards rather than physical artifacts, so the factor of 3465 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.
