About Converting Imperial gallon per Weeks to Gallon per Seconds
Imperial gallon per Weeks and Gallon 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
gallon per seconds = imperial gallon per weeks × 0.00000198569762815
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 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct imperial gallon per weeks-to-gallon per seconds factor of 0.00000198569762815.
Simple example
1 imp gal/wk × 0.000001985697628 = 0.0000019857 gal/s
1 imperial gallon per weeks = 0.0000019857 gallon per seconds.
Real-world example
60 imp gal/wk × 0.000001985697628 = 0.0001191419 gal/s
60 imperial gallon per weeks = 0.0001191419 gallon per seconds.

How do I convert gallon per seconds back to imperial gallon per weeks?
Use the reverse factor: 1 gallon per seconds equals 503,601.3469 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 gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the imperial gallon per weeks to gallon per seconds conversion exact?
Yes. Both imperial gallon per weeks and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.000001985697628 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.
