About Converting Cubic foot per Days to Imperial gallon per Hours
Cubic foot per Days and Imperial gallon per Hours 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 hours = cubic foot per days × 0.259534810793
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 hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct cubic foot per days-to-imperial gallon per hours factor of 0.259534810793.
Simple example
1 ft3/d × 0.2595348108 = 0.2595348108 imp gal/h
1 cubic foot per days = 0.2595348108 imperial gallon per hours.
Real-world example
60 ft3/d × 0.2595348108 = 15.57208865 imp gal/h
60 cubic foot per days = 15.57208865 imperial gallon per hours.

How do I convert imperial gallon per hours back to cubic foot per days?
Use the reverse factor: 1 imperial gallon per hours equals 3.853047678 cubic foot per days. You can also use the swap control in the converter above to flip the direction instantly.
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 hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
Is the cubic foot per days to imperial gallon per hours conversion exact?
Yes. Both cubic foot per days and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.2595348108 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.
