About Converting Cubic foot per Days to Gallon per Hours
Cubic foot per Days and 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
gallon per hours = cubic foot per days × 0.311688311688
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 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct cubic foot per days-to-gallon per hours factor of 0.311688311688.
Simple example
1 ft3/d × 0.3116883117 = 0.3116883117 gal/h
1 cubic foot per days = 0.3116883117 gallon per hours.
Real-world example
60 ft3/d × 0.3116883117 = 18.7012987 gal/h
60 cubic foot per days = 18.7012987 gallon per hours.

Multiply the cubic foot per days value by 0.3116883117. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to cubic foot per days?
Use the reverse factor: 1 gallon per hours equals 3.208333333 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 gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the cubic foot per days to gallon per hours conversion exact?
Yes. Both cubic foot per days and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.3116883117 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.
