About Converting Imperial gallon per Seconds to Cubic foot per Days
Imperial gallon per Seconds 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 seconds × 13870.9716396
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per seconds equals 0.00454609 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 seconds-to-cubic foot per days factor of 13870.9716396.
Simple example
1 imp gal/s × 13870.97164 = 13,870.97164 ft3/d
1 imperial gallon per seconds = 13,870.97164 cubic foot per days.
Real-world example
60 imp gal/s × 13870.97164 = 832,258.2984 ft3/d
60 imperial gallon per seconds = 832,258.2984 cubic foot per days.

Frequently asked questions
How many cubic foot per days are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 13,870.97164 cubic foot per days, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to cubic foot per days?
Multiply the imperial gallon per seconds value by 13870.97164. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per days back to imperial gallon per seconds?
Use the reverse factor: 1 cubic foot per days equals 0.000072093 imperial gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) 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 seconds to cubic foot per days conversion exact?
Yes. Both imperial gallon per seconds and cubic foot per days are defined by fixed standards rather than physical artifacts, so the factor of 13870.97164 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.
