About Converting Imperial gallon per Seconds to Cubic yard per Years
Imperial gallon per Seconds and Cubic yard per Years 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 years = imperial gallon per seconds × 187639.568854
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per seconds equals 0.00454609 base units, and 1 cubic yard per years equals 2.422778e-8 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-cubic yard per years factor of 187639.568854.
Simple example
1 imp gal/s × 187639.5689 = 187,639.5689 yd3/yr
1 imperial gallon per seconds = 187,639.5689 cubic yard per years.
Real-world example
60 imp gal/s × 187639.5689 = 11,258,374.13 yd3/yr
60 imperial gallon per seconds = 11,258,374.13 cubic yard per years.

Frequently asked questions
How many cubic yard per years are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 187,639.5689 cubic yard per years, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to cubic yard per years?
Multiply the imperial gallon per seconds value by 187639.5689. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per years back to imperial gallon per seconds?
Use the reverse factor: 1 cubic yard per years equals 0.0000053294 imperial gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
What is a cubic yard per years?
Cubic yard per Years (yd3/yr) is a unit of flow rate.
Is the imperial gallon per seconds to cubic yard per years conversion exact?
Yes. Both imperial gallon per seconds and cubic yard per years are defined by fixed standards rather than physical artifacts, so the factor of 187639.5689 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.
