About Converting Imperial quart per Seconds to Cubic inch per Seconds
Imperial quart per Seconds 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 = imperial quart per seconds × 69.3548581979
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per seconds equals 0.0011365225 base units, and 1 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct imperial quart per seconds-to-cubic inch per seconds factor of 69.3548581979.
Simple example
1 imp qt/s × 69.3548582 = 69.3548582 in3/s
1 imperial quart per seconds = 69.3548582 cubic inch per seconds.
Real-world example
60 imp qt/s × 69.3548582 = 4,161.291492 in3/s
60 imperial quart per seconds = 4,161.291492 cubic inch per seconds.

What is a imperial quart per seconds?
Imperial quart per Seconds (imp qt/s) 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 imperial quart per seconds to cubic inch per seconds conversion exact?
Yes. Both imperial quart per seconds and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 69.3548582 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.
