About Converting Gallons per Millisecond to Imperial gallon per Weeks
Gallon per Millisecond and Imperial gallon 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
imperial gallon per weeks = gallons per millisecond × 503601346.864
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 imperial gallon per weeks equals 7.516683e-9 base units, so dividing one by the other gives the direct gallon per millisecond-to-imperial gallon per weeks factor of 503601346.864.
Simple example
1 gal/ms × 503601346.9 = 503,601,346.9 imp gal/wk
1 gallon per millisecond = 503,601,346.9 imperial gallon per weeks.
Real-world example
60 gal/ms × 503601346.9 = 30,216,080,810 imp gal/wk
60 gallons per millisecond = 30,216,080,810 imperial gallon per weeks.

Frequently asked questions
How many imperial gallon per weeks are in 1 gallon per millisecond?
1 gallon per millisecond equals 503,601,346.9 imperial gallon per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to imperial gallon per weeks?
Multiply the gallon per millisecond value by 503601346.9. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per weeks back to gallon per millisecond?
Use the reverse factor: 1 imperial gallon per weeks equals 1.985698e-9 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
What is a imperial gallon per weeks?
Imperial gallon per Weeks (imp gal/wk) is a unit of flow rate.
Is the gallon per millisecond to imperial gallon per weeks conversion exact?
Yes. Both gallon per millisecond and imperial gallon per weeks are defined by fixed standards rather than physical artifacts, so the factor of 503601346.9 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.
