About Converting Cubic Millimeter per Weeks to Imperial gallon per Days
Cubic Millimeter per Weeks and Imperial gallon per Days 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 days = cubic millimeter per weeks × 3.142418e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per weeks equals 1.653439e-15 base units, and 1 imperial gallon per days equals 5.261678e-8 base units, so dividing one by the other gives the direct cubic millimeter per weeks-to-imperial gallon per days factor of 3.142418e-8.
Simple example
1 mm3/wk × 3.142418e-8 = 3.142418e-8 imp gal/d
1 cubic millimeter per weeks = 3.142418e-8 imperial gallon per days.
Real-world example
60 mm3/wk × 3.142418e-8 = 0.0000018855 imp gal/d
60 cubic millimeter per weeks = 0.0000018855 imperial gallon per days.

How do I convert imperial gallon per days back to cubic millimeter per weeks?
Use the reverse factor: 1 imperial gallon per days equals 31,822,630 cubic millimeter per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per weeks?
Cubic Millimeter per Weeks (mm3/wk) is a unit of flow rate.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
Is the cubic millimeter per weeks to imperial gallon per days conversion exact?
Yes. Both cubic millimeter per weeks and imperial gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 3.142418e-8 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.
