About Converting Cubic foot per Days to Cubic yard per Days
Cubic foot per Days and Cubic yard 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 yard per days = cubic foot per days × 0.037037037037
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 cubic yard per days equals 0.00000884901456 base units, so dividing one by the other gives the direct cubic foot per days-to-cubic yard per days factor of 0.037037037037.
Simple example
1 ft3/d × 0.03703703704 = 0.037037037 yd3/d
1 cubic foot per days = 0.037037037 cubic yard per days.
Real-world example
60 ft3/d × 0.03703703704 = 2.222222222 yd3/d
60 cubic foot per days = 2.222222222 cubic yard per days.

Multiply the cubic foot per days value by 0.03703703704. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per days back to cubic foot per days?
Use the reverse factor: 1 cubic yard per days equals 27 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 cubic yard per days?
Cubic yard per Days (yd3/d) is a unit of flow rate.
Is the cubic foot per days to cubic yard per days conversion exact?
Yes. Both cubic foot per days and cubic yard per days are defined by fixed standards rather than physical artifacts, so the factor of 0.03703703704 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.
