About Converting Imperial quart per Days to Cubic inch per Seconds
Imperial 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 = imperial quart per days × 0.000802718266179
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 seconds equals 0.000016387064 base units, so dividing one by the other gives the direct imperial quart per days-to-cubic inch per seconds factor of 0.000802718266179.
Simple example
1 imp qt/d × 0.0008027182662 = 0.0008027183 in3/s
1 imperial quart per days = 0.0008027183 cubic inch per seconds.
Real-world example
60 imp qt/d × 0.0008027182662 = 0.048163096 in3/s
60 imperial quart per days = 0.048163096 cubic inch per seconds.

How do I convert cubic inch per seconds back to imperial quart per days?
Use the reverse factor: 1 cubic inch per seconds equals 1,245.767092 imperial quart per days. You can also use the swap control in the converter above to flip the direction instantly.
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 seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the imperial quart per days to cubic inch per seconds conversion exact?
Yes. Both imperial quart per days and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0008027182662 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.
