About Converting Cubic inch per Seconds to Quart per Minutes
Cubic inch per Seconds 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 seconds × 1.03896103896
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 quart per minutes equals 0.0000157725491 base units, so dividing one by the other gives the direct cubic inch per seconds-to-quart per minutes factor of 1.03896103896.
Simple example
1 in3/s × 1.038961039 = 1.038961039 qt/min
1 cubic inch per seconds = 1.038961039 quart per minutes.
Real-world example
60 in3/s × 1.038961039 = 62.33766234 qt/min
60 cubic inch per seconds = 62.33766234 quart per minutes.

Frequently asked questions
How many quart per minutes are in 1 cubic inch per seconds?
1 cubic inch per seconds equals 1.038961039 quart per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per seconds to quart per minutes?
Multiply the cubic inch per seconds value by 1.038961039. The converter above does this instantly to whatever precision you set.
How do I convert quart per minutes back to cubic inch per seconds?
Use the reverse factor: 1 quart per minutes equals 0.9625 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 quart per minutes?
Quart per Minutes (qt/min) is a unit of flow rate.
Is the cubic inch per seconds to quart per minutes conversion exact?
Yes. Both cubic inch per seconds and quart per minutes are defined by fixed standards rather than physical artifacts, so the factor of 1.038961039 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.
