About Converting Cubic foot per Years to Cup per Seconds
Cubic foot per Years 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 foot per years × 0.00000379277161141
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per years equals 8.973251e-10 base units, and 1 cup per seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct cubic foot per years-to-cup per seconds factor of 0.00000379277161141.
Simple example
1 ft3/yr × 0.000003792771611 = 0.0000037928 cup/s
1 cubic foot per years = 0.0000037928 cup per seconds.
Real-world example
60 ft3/yr × 0.000003792771611 = 0.0002275663 cup/s
60 cubic foot per years = 0.0002275663 cup per seconds.

Frequently asked questions
How many cup per seconds are in 1 cubic foot per years?
1 cubic foot per years equals 0.0000037928 cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per years to cup per seconds?
Multiply the cubic foot per years value by 0.000003792771611. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to cubic foot per years?
Use the reverse factor: 1 cup per seconds equals 263,659.4297 cubic foot per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per years?
Cubic foot per Years (ft3/yr) 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 foot per years to cup per seconds conversion exact?
Yes. Both cubic foot per years and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.000003792771611 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.
