About Converting Imperial gallon per Years to Cubic foot per Days
Imperial gallon per Years and Cubic foot per Days 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 foot per days = imperial gallon per years × 0.000439553593122
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per years equals 1.440599e-10 base units, and 1 cubic foot per days equals 3.277413e-7 base units, so dividing one by the other gives the direct imperial gallon per years-to-cubic foot per days factor of 0.000439553593122.
Simple example
1 imp gal/yr × 0.0004395535931 = 0.0004395536 ft3/d
1 imperial gallon per years = 0.0004395536 cubic foot per days.
Real-world example
60 imp gal/yr × 0.0004395535931 = 0.0263732156 ft3/d
60 imperial gallon per years = 0.0263732156 cubic foot per days.

How do I convert cubic foot per days back to imperial gallon per years?
Use the reverse factor: 1 cubic foot per days equals 2,275.035435 imperial gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
What is a cubic foot per days?
Cubic foot per Days (ft3/d) is a unit of flow rate.
Is the imperial gallon per years to cubic foot per days conversion exact?
Yes. Both imperial gallon per years and cubic foot per days are defined by fixed standards rather than physical artifacts, so the factor of 0.0004395535931 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.
