About Converting Quart per Seconds to Cubic inch per Days
Quart per Seconds 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 = quart per seconds × 4989600
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per seconds equals 0.000946352946 base units, and 1 cubic inch per days equals 1.896651e-10 base units, so dividing one by the other gives the direct quart per seconds-to-cubic inch per days factor of 4989600.
Simple example
1 qt/s × 4989600 = 4,989,600 in3/d
1 quart per seconds = 4,989,600 cubic inch per days.
Real-world example
60 qt/s × 4989600 = 299,376,000 in3/d
60 quart per seconds = 299,376,000 cubic inch per days.

Frequently asked questions
How many cubic inch per days are in 1 quart per seconds?
1 quart per seconds equals 4,989,600 cubic inch per days, using the exact defined conversion factor rather than an estimate.
How do I convert quart per seconds to cubic inch per days?
Multiply the quart per seconds value by 4989600. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per days back to quart per seconds?
Use the reverse factor: 1 cubic inch per days equals 2.004169e-7 quart per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per seconds?
Quart per Seconds (qt/s) 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 quart per seconds to cubic inch per days conversion exact?
Yes. Both quart per seconds and cubic inch per days are defined by fixed standards rather than physical artifacts, so the factor of 4989600 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.
