About Converting Cubic Millimeter per Weeks to Imperial gallons per Millisecond
Cubic Millimeter per Weeks and Imperial gallon per Millisecond 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 gallons per millisecond = cubic millimeter per weeks × 3.637058e-16
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 millisecond equals 4.54609 base units, so dividing one by the other gives the direct cubic millimeter per weeks-to-imperial gallon per millisecond factor of 3.637058e-16.
Simple example
1 mm3/wk × 3.637058e-16 = 3.637058e-16 imp gal/ms
1 cubic millimeter per weeks = 3.637058e-16 imperial gallons per millisecond.
Real-world example
60 mm3/wk × 3.637058e-16 = 2.182235e-14 imp gal/ms
60 cubic millimeter per weeks = 2.182235e-14 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 cubic millimeter per weeks?
1 cubic millimeter per weeks equals 3.637058e-16 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per weeks to imperial gallon per millisecond?
Multiply the cubic millimeter per weeks value by 3.637058e-16. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to cubic millimeter per weeks?
Use the reverse factor: 1 imperial gallon per millisecond equals 2.749475e+15 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 millisecond?
Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.
Is the cubic millimeter per weeks to imperial gallon per millisecond conversion exact?
Yes. Both cubic millimeter per weeks and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 3.637058e-16 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.
