About Converting Imperial gallon per Years to Cubic Millimeter per Seconds
Imperial gallon per Years and Cubic Millimeter per Seconds 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 seconds = imperial gallon per years × 0.144059857238
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 seconds equals 1e-9 base units, so dividing one by the other gives the direct imperial gallon per years-to-cubic millimeter per seconds factor of 0.144059857238.
Simple example
1 imp gal/yr × 0.1440598572 = 0.1440598572 mm3/s
1 imperial gallon per years = 0.1440598572 cubic millimeter per seconds.
Real-world example
60 imp gal/yr × 0.1440598572 = 8.643591434 mm3/s
60 imperial gallon per years = 8.643591434 cubic millimeter per seconds.

Frequently asked questions
How many cubic millimeter per seconds are in 1 imperial gallon per years?
1 imperial gallon per years equals 0.1440598572 cubic millimeter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per years to cubic millimeter per seconds?
Multiply the imperial gallon per years value by 0.1440598572. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per seconds back to imperial gallon per years?
Use the reverse factor: 1 cubic millimeter per seconds equals 6.94155901 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 seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
Is the imperial gallon per years to cubic millimeter per seconds conversion exact?
Yes. Both imperial gallon per years and cubic millimeter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.1440598572 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.
