About Converting Hectoliter per Years to Imperial gallon per Years
Hectoliter per Years and Imperial 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
imperial gallon per years = hectoliter per years × 21.9969248299
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per years equals 3.168874e-9 base units, and 1 imperial gallon per years equals 1.440599e-10 base units, so dividing one by the other gives the direct hectoliter per years-to-imperial gallon per years factor of 21.9969248299.
Simple example
1 hL/yr × 21.99692483 = 21.99692483 imp gal/yr
1 hectoliter per years = 21.99692483 imperial gallon per years.
Real-world example
60 hL/yr × 21.99692483 = 1,319.81549 imp gal/yr
60 hectoliter per years = 1,319.81549 imperial gallon per years.

Frequently asked questions
How many imperial gallon per years are in 1 hectoliter per years?
1 hectoliter per years equals 21.99692483 imperial gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per years to imperial gallon per years?
Multiply the hectoliter per years value by 21.99692483. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per years back to hectoliter per years?
Use the reverse factor: 1 imperial gallon per years equals 0.0454609 hectoliter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per years?
Hectoliter per Years (hL/yr) is a unit of flow rate.
What is a imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
Is the hectoliter per years to imperial gallon per years conversion exact?
Yes. Both hectoliter per years and imperial gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 21.99692483 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.
