About Converting Cup per Years to Metric cup per Seconds
Cup per Years and Metric 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
metric cup per seconds = cup per years × 2.998873e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per years equals 7.497183e-12 base units, and 1 metric cup per seconds equals 0.00025 base units, so dividing one by the other gives the direct cup per years-to-metric cup per seconds factor of 2.998873e-8.
Simple example
1 cup/yr × 2.998873e-8 = 2.998873e-8 metric cup/s
1 cup per years = 2.998873e-8 metric cup per seconds.
Real-world example
60 cup/yr × 2.998873e-8 = 0.0000017993 metric cup/s
60 cup per years = 0.0000017993 metric cup per seconds.

Frequently asked questions
How many metric cup per seconds are in 1 cup per years?
1 cup per years equals 2.998873e-8 metric cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per years to metric cup per seconds?
Multiply the cup per years value by 2.998873e-8. The converter above does this instantly to whatever precision you set.
How do I convert metric cup per seconds back to cup per years?
Use the reverse factor: 1 metric cup per seconds equals 33,345,859.1 cup per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per years?
Cup per Years (cup/yr) is a unit of flow rate.
What is a metric cup per seconds?
Metric cup per Seconds (metric cup/s) is a unit of flow rate.
Is the cup per years to metric cup per seconds conversion exact?
Yes. Both cup per years and metric cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 2.998873e-8 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.
