About Converting Imperial gallon per Days to Cubic inch per Seconds
Imperial gallon 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 gallon per days × 0.00321087306472
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per days equals 5.261678e-8 base units, and 1 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct imperial gallon per days-to-cubic inch per seconds factor of 0.00321087306472.
Simple example
1 imp gal/d × 0.003210873065 = 0.0032108731 in3/s
1 imperial gallon per days = 0.0032108731 cubic inch per seconds.
Real-world example
60 imp gal/d × 0.003210873065 = 0.1926523839 in3/s
60 imperial gallon per days = 0.1926523839 cubic inch per seconds.

Frequently asked questions
How many cubic inch per seconds are in 1 imperial gallon per days?
1 imperial gallon per days equals 0.0032108731 cubic inch per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per days to cubic inch per seconds?
Multiply the imperial gallon per days value by 0.003210873065. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to imperial gallon per days?
Use the reverse factor: 1 cubic inch per seconds equals 311.441773 imperial gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/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 gallon per days to cubic inch per seconds conversion exact?
Yes. Both imperial gallon per days and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.003210873065 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.
