About Converting Gallon per Days to Cubic foot per Days
Gallon per Days 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 = gallon per days × 0.133680555556
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 cubic foot per days equals 3.277413e-7 base units, so dividing one by the other gives the direct gallon per days-to-cubic foot per days factor of 0.133680555556.
Simple example
1 gal/d × 0.1336805556 = 0.1336805556 ft3/d
1 gallon per days = 0.1336805556 cubic foot per days.
Real-world example
60 gal/d × 0.1336805556 = 8.020833333 ft3/d
60 gallon per days = 8.020833333 cubic foot per days.

Multiply the gallon per days value by 0.1336805556. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per days back to gallon per days?
Use the reverse factor: 1 cubic foot per days equals 7.480519481 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) 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 gallon per days to cubic foot per days conversion exact?
Yes. Both gallon per days and cubic foot per days are defined by fixed standards rather than physical artifacts, so the factor of 0.1336805556 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.
