About Converting Cubic foot per Seconds to Imperial gallon per Months
Cubic foot per Seconds and Imperial gallon per Months 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 Seconds is most often used for the standard unit used by the us geological survey for reporting river and stream discharge at gauging stations.
Formula
imperial gallon per months = cubic foot per seconds × 16380255.1331
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per seconds equals 0.028316846592 base units, and 1 imperial gallon per months equals 1.728718e-9 base units, so dividing one by the other gives the direct cubic foot per seconds-to-imperial gallon per months factor of 16380255.1331.
Simple example
1 ft3/s × 16380255.13 = 16,380,255.13 imp gal/mo
1 cubic foot per seconds = 16,380,255.13 imperial gallon per months.
Real-world example
60 ft3/s × 16380255.13 = 982,815,308 imp gal/mo
60 cubic foot per seconds = 982,815,308 imperial gallon per months.

Where is the cubic foot per seconds still used today?
United States
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.
