About Converting Imperial quart per Days to Cubic inch per Days
Imperial quart per Days and Cubic inch per Days 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 days = imperial quart per days × 69.3548581979
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per days equals 1.31542e-8 base units, and 1 cubic inch per days equals 1.896651e-10 base units, so dividing one by the other gives the direct imperial quart per days-to-cubic inch per days factor of 69.3548581979.
Simple example
1 imp qt/d × 69.3548582 = 69.3548582 in3/d
1 imperial quart per days = 69.3548582 cubic inch per days.
Real-world example
60 imp qt/d × 69.3548582 = 4,161.291492 in3/d
60 imperial quart per days = 4,161.291492 cubic inch per days.

What is a imperial quart per days?
Imperial quart per Days (imp qt/d) is a unit of flow rate.
What is a cubic inch per days?
Cubic inch per Days (in3/d) is a unit of flow rate.
Is the imperial quart per days to cubic inch per days conversion exact?
Yes. Both imperial quart per days and cubic inch per days 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.
