About Converting Quart per Days to Cubic inch per Seconds
Quart per Days 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 = quart per days × 0.000668402777778
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct quart per days-to-cubic inch per seconds factor of 0.000668402777778.
Simple example
1 qt/d × 0.0006684027778 = 0.0006684028 in3/s
1 quart per days = 0.0006684028 cubic inch per seconds.
Real-world example
60 qt/d × 0.0006684027778 = 0.0401041667 in3/s
60 quart per days = 0.0401041667 cubic inch per seconds.

Frequently asked questions
How many cubic inch per seconds are in 1 quart per days?
1 quart per days equals 0.0006684028 cubic inch per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to cubic inch per seconds?
Multiply the quart per days value by 0.0006684027778. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to quart per days?
Use the reverse factor: 1 cubic inch per seconds equals 1,496.103896 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/d) 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 quart per days to cubic inch per seconds conversion exact?
Yes. Both quart per days and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0006684027778 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.
