About Converting Cup per Years to Imperial gallon per Seconds
Cup per Years and Imperial gallon 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
imperial gallon per seconds = cup per years × 1.64915e-9
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 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct cup per years-to-imperial gallon per seconds factor of 1.64915e-9.
Simple example
1 cup/yr × 1.64915e-9 = 1.64915e-9 imp gal/s
1 cup per years = 1.64915e-9 imperial gallon per seconds.
Real-world example
60 cup/yr × 1.64915e-9 = 9.894898e-8 imp gal/s
60 cup per years = 9.894898e-8 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 cup per years?
1 cup per years equals 1.64915e-9 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per years to imperial gallon per seconds?
Multiply the cup per years value by 1.64915e-9. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to cup per years?
Use the reverse factor: 1 imperial gallon per seconds equals 606,373,106.5 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 imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the cup per years to imperial gallon per seconds conversion exact?
Yes. Both cup per years and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.64915e-9 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.
