About Converting Cubic inch per Days to Imperial gallon per Minutes
Cubic inch per Days and Imperial gallon per Minutes 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
imperial gallon per minutes = cubic inch per days × 0.00000250322927077
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per days equals 1.896651e-10 base units, and 1 imperial gallon per minutes equals 0.0000757681666667 base units, so dividing one by the other gives the direct cubic inch per days-to-imperial gallon per minutes factor of 0.00000250322927077.
Simple example
1 in3/d × 0.000002503229271 = 0.0000025032 imp gal/min
1 cubic inch per days = 0.0000025032 imperial gallon per minutes.
Real-world example
60 in3/d × 0.000002503229271 = 0.0001501938 imp gal/min
60 cubic inch per days = 0.0001501938 imperial gallon per minutes.

What is a cubic inch per days?
Cubic inch per Days (in3/d) is a unit of flow rate.
What is a imperial gallon per minutes?
Imperial gallon per Minutes (imp gal/min) is a unit of flow rate.
Is the cubic inch per days to imperial gallon per minutes conversion exact?
Yes. Both cubic inch per days and imperial gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.000002503229271 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.
