About Converting Cubic foot per Minutes to Imperial gallon per Days
Cubic foot per Minutes 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. Cubic foot per Minutes is most often used for the standard unit for rating hvac airflow, compressed-air equipment output, and fan/blower performance.
Formula
imperial gallon per days = cubic foot per minutes × 8969.52306102
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per minutes equals 0.0004719474432 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 minutes-to-imperial gallon per days factor of 8969.52306102.
Simple example
1 ft3/min × 8969.523061 = 8,969.523061 imp gal/d
1 cubic foot per minutes = 8,969.523061 imperial gallon per days.
Real-world example
60 ft3/min × 8969.523061 = 538,171.3837 imp gal/d
60 cubic foot per minutes = 538,171.3837 imperial gallon per days.

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.
