About Converting Imperial gallon per Decades to Gallon per Years
Imperial gallon per Decades and Gallon 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
gallon per years = imperial gallon per decades × 0.12009499255
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per decades equals 1.440599e-11 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct imperial gallon per decades-to-gallon per years factor of 0.12009499255.
Simple example
1 imp gal/decade × 0.1200949926 = 0.1200949926 gal/yr
1 imperial gallon per decades = 0.1200949926 gallon per years.
Real-world example
60 imp gal/decade × 0.1200949926 = 7.205699553 gal/yr
60 imperial gallon per decades = 7.205699553 gallon per years.

Frequently asked questions
How many gallon per years are in 1 imperial gallon per decades?
1 imperial gallon per decades equals 0.1200949926 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per decades to gallon per years?
Multiply the imperial gallon per decades value by 0.1200949926. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to imperial gallon per decades?
Use the reverse factor: 1 gallon per years equals 8.326741846 imperial gallon per decades. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per decades?
Imperial gallon per Decades (imp gal/decade) is a unit of flow rate.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
Is the imperial gallon per decades to gallon per years conversion exact?
Yes. Both imperial gallon per decades and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 0.1200949926 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.
