About Converting Cubic Millimeter per Hours to Gallon per Years
Cubic Millimeter 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 = cubic millimeter per hours × 0.00231568466
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per hours equals 2.777778e-13 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct cubic millimeter per hours-to-gallon per years factor of 0.00231568466.
Simple example
1 mm3/h × 0.00231568466 = 0.0023156847 gal/yr
1 cubic millimeter per hours = 0.0023156847 gallon per years.
Real-world example
60 mm3/h × 0.00231568466 = 0.1389410796 gal/yr
60 cubic millimeter per hours = 0.1389410796 gallon per years.

Frequently asked questions
How many gallon per years are in 1 cubic millimeter per hours?
1 cubic millimeter per hours equals 0.0023156847 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per hours to gallon per years?
Multiply the cubic millimeter per hours value by 0.00231568466. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to cubic millimeter per hours?
Use the reverse factor: 1 gallon per years equals 431.837727 cubic millimeter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per hours?
Cubic Millimeter per Hours (mm3/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 cubic millimeter per hours to gallon per years conversion exact?
Yes. Both cubic millimeter per hours and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 0.00231568466 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.
