About Converting Imperial gallon per Weeks to Cubic Millimeter per Weeks
Imperial gallon per Weeks and Cubic Millimeter per Weeks 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 weeks = imperial gallon per weeks × 4546090
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per weeks equals 7.516683e-9 base units, and 1 cubic millimeter per weeks equals 1.653439e-15 base units, so dividing one by the other gives the direct imperial gallon per weeks-to-cubic millimeter per weeks factor of 4546090.
Simple example
1 imp gal/wk × 4546090 = 4,546,090 mm3/wk
1 imperial gallon per weeks = 4,546,090 cubic millimeter per weeks.
Real-world example
60 imp gal/wk × 4546090 = 272,765,400 mm3/wk
60 imperial gallon per weeks = 272,765,400 cubic millimeter per weeks.

Frequently asked questions
How many cubic millimeter per weeks are in 1 imperial gallon per weeks?
1 imperial gallon per weeks equals 4,546,090 cubic millimeter per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per weeks to cubic millimeter per weeks?
Multiply the imperial gallon per weeks value by 4546090. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per weeks back to imperial gallon per weeks?
Use the reverse factor: 1 cubic millimeter per weeks equals 2.199692e-7 imperial gallon per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per weeks?
Imperial gallon per Weeks (imp gal/wk) is a unit of flow rate.
What is a cubic millimeter per weeks?
Cubic Millimeter per Weeks (mm3/wk) is a unit of flow rate.
Is the imperial gallon per weeks to cubic millimeter per weeks conversion exact?
Yes. Both imperial gallon per weeks and cubic millimeter per weeks are defined by fixed standards rather than physical artifacts, so the factor of 4546090 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.
