About Converting Milliliter per Hours to Gallon per Years
Milliliter per Hours 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 = milliliter per hours × 2.31568466
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per hours equals 2.777778e-10 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct milliliter per hours-to-gallon per years factor of 2.31568466.
Simple example
1 mL/h × 2.31568466 = 2.31568466 gal/yr
1 milliliter per hours = 2.31568466 gallon per years.
Real-world example
60 mL/h × 2.31568466 = 138.9410796 gal/yr
60 milliliter per hours = 138.9410796 gallon per years.

Frequently asked questions
How many gallon per years are in 1 milliliter per hours?
1 milliliter per hours equals 2.31568466 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to gallon per years?
Multiply the milliliter per hours value by 2.31568466. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to milliliter per hours?
Use the reverse factor: 1 gallon per years equals 0.431837727 milliliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per hours?
Milliliter per Hours (mL/h) 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 milliliter per hours to gallon per years conversion exact?
Yes. Both milliliter per hours and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 2.31568466 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.
