About Converting Hectoliter per Years to Gallon per Years
Hectoliter per Years 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 = hectoliter per years × 26.4172052358
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 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct hectoliter per years-to-gallon per years factor of 26.4172052358.
Simple example
1 hL/yr × 26.41720524 = 26.41720524 gal/yr
1 hectoliter per years = 26.41720524 gallon per years.
Real-world example
60 hL/yr × 26.41720524 = 1,585.032314 gal/yr
60 hectoliter per years = 1,585.032314 gallon per years.

Frequently asked questions
How many gallon per years are in 1 hectoliter per years?
1 hectoliter per years equals 26.41720524 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per years to gallon per years?
Multiply the hectoliter per years value by 26.41720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to hectoliter per years?
Use the reverse factor: 1 gallon per years equals 0.0378541178 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 gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
Is the hectoliter per years to gallon per years conversion exact?
Yes. Both hectoliter per years and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 26.41720524 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.
