About Converting Cubic Millimeter per Days to Imperial gallon per Years
Cubic Millimeter per Days and Imperial 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
imperial gallon per years = cubic millimeter per days × 0.0000803421181719
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per days equals 1.157407e-14 base units, and 1 imperial gallon per years equals 1.440599e-10 base units, so dividing one by the other gives the direct cubic millimeter per days-to-imperial gallon per years factor of 0.0000803421181719.
Simple example
1 mm3/d × 0.00008034211817 = 0.0000803421 imp gal/yr
1 cubic millimeter per days = 0.0000803421 imperial gallon per years.
Real-world example
60 mm3/d × 0.00008034211817 = 0.0048205271 imp gal/yr
60 cubic millimeter per days = 0.0048205271 imperial gallon per years.

Frequently asked questions
How many imperial gallon per years are in 1 cubic millimeter per days?
1 cubic millimeter per days equals 0.0000803421 imperial gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per days to imperial gallon per years?
Multiply the cubic millimeter per days value by 0.00008034211817. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per years back to cubic millimeter per days?
Use the reverse factor: 1 imperial gallon per years equals 12,446.77167 cubic millimeter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per days?
Cubic Millimeter per Days (mm3/d) is a unit of flow rate.
What is a imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
Is the cubic millimeter per days to imperial gallon per years conversion exact?
Yes. Both cubic millimeter per days and imperial gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 0.00008034211817 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.
