About Converting Cup per Days to Cubic yard per Hours
Cup per Days and Cubic yard 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
cubic yard per hours = cup per days × 0.0000128935721022
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 hours equals 0.00021237634944 base units, so dividing one by the other gives the direct cup per days-to-cubic yard per hours factor of 0.0000128935721022.
Simple example
1 cup/d × 0.0000128935721 = 0.0000128936 yd3/h
1 cup per days = 0.0000128936 cubic yard per hours.
Real-world example
60 cup/d × 0.0000128935721 = 0.0007736143 yd3/h
60 cup per days = 0.0007736143 cubic yard per hours.

What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
What is a cubic yard per hours?
Cubic yard per Hours (yd3/h) is a unit of flow rate.
Is the cup per days to cubic yard per hours conversion exact?
Yes. Both cup per days and cubic yard per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.0000128935721 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.
