About Converting Cubic inch per Days to Imperial gallon per Years
Cubic inch per Days and Imperial gallon per Years 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 years = cubic inch per days × 1.31657143238
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 years equals 1.440599e-10 base units, so dividing one by the other gives the direct cubic inch per days-to-imperial gallon per years factor of 1.31657143238.
Simple example
1 in3/d × 1.316571432 = 1.316571432 imp gal/yr
1 cubic inch per days = 1.316571432 imperial gallon per years.
Real-world example
60 in3/d × 1.316571432 = 78.99428594 imp gal/yr
60 cubic inch per days = 78.99428594 imperial gallon per years.

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 years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
Is the cubic inch per days to imperial gallon per years conversion exact?
Yes. Both cubic inch per days and imperial gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 1.316571432 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.
