About Converting Gallon per Years to Imperial gallon per Seconds
Gallon 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 = gallon per years × 2.638639e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per years equals 1.199549e-10 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct gallon per years-to-imperial gallon per seconds factor of 2.638639e-8.
Simple example
1 gal/yr × 2.638639e-8 = 2.638639e-8 imp gal/s
1 gallon per years = 2.638639e-8 imperial gallon per seconds.
Real-world example
60 gal/yr × 2.638639e-8 = 0.0000015832 imp gal/s
60 gallon per years = 0.0000015832 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 gallon per years?
1 gallon per years equals 2.638639e-8 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per years to imperial gallon per seconds?
Multiply the gallon per years value by 2.638639e-8. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to gallon per years?
Use the reverse factor: 1 imperial gallon per seconds equals 37,898,319.15 gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per years?
Gallon per Years (gal/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 gallon per years to imperial gallon per seconds conversion exact?
Yes. Both gallon per years and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 2.638639e-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.
