About Converting Cubic foot per Days to Imperial gallon per Days
Cubic foot per Days and Imperial gallon 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
imperial gallon per days = cubic foot per days × 6.22883545904
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per days equals 3.277413e-7 base units, and 1 imperial gallon per days equals 5.261678e-8 base units, so dividing one by the other gives the direct cubic foot per days-to-imperial gallon per days factor of 6.22883545904.
Simple example
1 ft3/d × 6.228835459 = 6.228835459 imp gal/d
1 cubic foot per days = 6.228835459 imperial gallon per days.
Real-world example
60 ft3/d × 6.228835459 = 373.7301275 imp gal/d
60 cubic foot per days = 373.7301275 imperial gallon per days.

What is a cubic foot per days?
Cubic foot per Days (ft3/d) is a unit of flow rate.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
Is the cubic foot per days to imperial gallon per days conversion exact?
Yes. Both cubic foot per days and imperial gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 6.228835459 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.
