About Converting Imperial gallon per Hours to Liter per Years
Imperial gallon per Hours and Liter 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
liter per years = imperial gallon per hours × 39850.2066438
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per hours equals 0.00000126280277778 base units, and 1 liter per years equals 3.168874e-11 base units, so dividing one by the other gives the direct imperial gallon per hours-to-liter per years factor of 39850.2066438.
Simple example
1 imp gal/h × 39850.20664 = 39,850.20664 L/yr
1 imperial gallon per hours = 39,850.20664 liter per years.
Real-world example
60 imp gal/h × 39850.20664 = 2,391,012.399 L/yr
60 imperial gallon per hours = 2,391,012.399 liter per years.

Frequently asked questions
How many liter per years are in 1 imperial gallon per hours?
1 imperial gallon per hours equals 39,850.20664 liter per years, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per hours to liter per years?
Multiply the imperial gallon per hours value by 39850.20664. The converter above does this instantly to whatever precision you set.
How do I convert liter per years back to imperial gallon per hours?
Use the reverse factor: 1 liter per years equals 0.000025094 imperial gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a liter per years?
Liter per Years (L/yr) is a unit of flow rate.
Is the imperial gallon per hours to liter per years conversion exact?
Yes. Both imperial gallon per hours and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 39850.20664 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.
