About Converting Cup per Seconds to Cubic yard per Seconds
Cup per Seconds and Cubic yard 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
cubic yard per seconds = cup per seconds × 0.000309445730453
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per seconds equals 0.0002365882365 base units, and 1 cubic yard per seconds equals 0.764554857984 base units, so dividing one by the other gives the direct cup per seconds-to-cubic yard per seconds factor of 0.000309445730453.
Simple example
1 cup/s × 0.0003094457305 = 0.0003094457 yd3/s
1 cup per seconds = 0.0003094457 cubic yard per seconds.
Real-world example
60 cup/s × 0.0003094457305 = 0.0185667438 yd3/s
60 cup per seconds = 0.0185667438 cubic yard per seconds.

Frequently asked questions
How many cubic yard per seconds are in 1 cup per seconds?
1 cup per seconds equals 0.0003094457 cubic yard per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per seconds to cubic yard per seconds?
Multiply the cup per seconds value by 0.0003094457305. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per seconds back to cup per seconds?
Use the reverse factor: 1 cubic yard per seconds equals 3,231.584416 cup per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
What is a cubic yard per seconds?
Cubic yard per Seconds (yd3/s) is a unit of flow rate.
Is the cup per seconds to cubic yard per seconds conversion exact?
Yes. Both cup per seconds and cubic yard per seconds 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.
