About Converting Cubic yard per Seconds to Cup per Seconds
Cubic yard per Seconds and Cup per Seconds 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 seconds = cubic yard per seconds × 3231.58441558
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 seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct cubic yard per seconds-to-cup per seconds factor of 3231.58441558.
Simple example
1 yd3/s × 3231.584416 = 3,231.584416 cup/s
1 cubic yard per seconds = 3,231.584416 cup per seconds.
Real-world example
60 yd3/s × 3231.584416 = 193,895.0649 cup/s
60 cubic yard per seconds = 193,895.0649 cup per seconds.

Frequently asked questions
How many cup per seconds are in 1 cubic yard per seconds?
1 cubic yard per seconds equals 3,231.584416 cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per seconds to cup per seconds?
Multiply the cubic yard per seconds value by 3231.584416. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to cubic yard per seconds?
Use the reverse factor: 1 cup per seconds equals 0.0003094457 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 seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
Is the cubic yard per seconds to cup per seconds conversion exact?
Yes. Both cubic yard per seconds and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 3231.584416 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.
