About Converting Imperial gallon per Years to Cubic Millimeter per Hours
Imperial gallon per Years and Cubic Millimeter per Hours 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
cubic millimeter per hours = imperial gallon per years × 518.615486058
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per years equals 1.440599e-10 base units, and 1 cubic millimeter per hours equals 2.777778e-13 base units, so dividing one by the other gives the direct imperial gallon per years-to-cubic millimeter per hours factor of 518.615486058.
Simple example
1 imp gal/yr × 518.6154861 = 518.6154861 mm3/h
1 imperial gallon per years = 518.6154861 cubic millimeter per hours.
Real-world example
60 imp gal/yr × 518.6154861 = 31,116.92916 mm3/h
60 imperial gallon per years = 31,116.92916 cubic millimeter per hours.

Multiply the imperial gallon per years value by 518.6154861. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per hours back to imperial gallon per years?
Use the reverse factor: 1 cubic millimeter per hours equals 0.0019282108 imperial gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
What is a cubic millimeter per hours?
Cubic Millimeter per Hours (mm3/h) is a unit of flow rate.
Is the imperial gallon per years to cubic millimeter per hours conversion exact?
Yes. Both imperial gallon per years and cubic millimeter per hours are defined by fixed standards rather than physical artifacts, so the factor of 518.6154861 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.
