About Converting Quart per Years to Cup per Seconds
Quart 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 = quart per years × 1.26755e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per years equals 2.998873e-11 base units, and 1 cup per seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct quart per years-to-cup per seconds factor of 1.26755e-7.
Simple example
1 qt/yr × 1.26755e-7 = 1.26755e-7 cup/s
1 quart per years = 1.26755e-7 cup per seconds.
Real-world example
60 qt/yr × 1.26755e-7 = 0.0000076053 cup/s
60 quart per years = 0.0000076053 cup per seconds.

Frequently asked questions
How many cup per seconds are in 1 quart per years?
1 quart per years equals 1.26755e-7 cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per years to cup per seconds?
Multiply the quart per years value by 1.26755e-7. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to quart per years?
Use the reverse factor: 1 cup per seconds equals 7,889,238 quart per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per years?
Quart per Years (qt/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 quart per years to cup per seconds conversion exact?
Yes. Both quart per years and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.26755e-7 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.
