About Converting Cubic yard per Seconds to Cup per Days
Cubic yard per Seconds and Cup 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
cup per days = cubic yard per seconds × 279208893.506
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per seconds equals 0.764554857984 base units, and 1 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct cubic yard per seconds-to-cup per days factor of 279208893.506.
Simple example
1 yd3/s × 279208893.5 = 279,208,893.5 cup/d
1 cubic yard per seconds = 279,208,893.5 cup per days.
Real-world example
60 yd3/s × 279208893.5 = 16,752,533,610 cup/d
60 cubic yard per seconds = 16,752,533,610 cup per days.

Frequently asked questions
How many cup per days are in 1 cubic yard per seconds?
1 cubic yard per seconds equals 279,208,893.5 cup per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per seconds to cup per days?
Multiply the cubic yard per seconds value by 279208893.5. The converter above does this instantly to whatever precision you set.
How do I convert cup per days back to cubic yard per seconds?
Use the reverse factor: 1 cup per days equals 3.581548e-9 cubic yard per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per seconds?
Cubic yard per Seconds (yd3/s) is a unit of flow rate.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the cubic yard per seconds to cup per days conversion exact?
Yes. Both cubic yard per seconds and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 279208893.5 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.
