About Converting Cup per Days to Cubic yard per Days
Cup 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 = cup per days × 0.000309445730453
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 cubic yard per days equals 0.00000884901456 base units, so dividing one by the other gives the direct cup per days-to-cubic yard per days factor of 0.000309445730453.
Simple example
1 cup/d × 0.0003094457305 = 0.0003094457 yd3/d
1 cup per days = 0.0003094457 cubic yard per days.
Real-world example
60 cup/d × 0.0003094457305 = 0.0185667438 yd3/d
60 cup per days = 0.0185667438 cubic yard per days.

How do I convert cubic yard per days back to cup per days?
Use the reverse factor: 1 cubic yard per days equals 3,231.584416 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/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 cup per days to cubic yard per days conversion exact?
Yes. Both cup per days and cubic yard per days are defined by fixed standards rather than physical artifacts, so the factor of 0.0003094457305 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.
