About Converting Gallon per Seconds to Cubic foot per Weeks
Gallon per Seconds and Cubic foot 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 foot per weeks = gallon per seconds × 80850
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 cubic foot per weeks equals 4.682018e-8 base units, so dividing one by the other gives the direct gallon per seconds-to-cubic foot per weeks factor of 80850.
Simple example
1 gal/s × 80850 = 80,850 ft3/wk
1 gallon per seconds = 80,850 cubic foot per weeks.
Real-world example
60 gal/s × 80850 = 4,851,000 ft3/wk
60 gallon per seconds = 4,851,000 cubic foot per weeks.

Frequently asked questions
How many cubic foot per weeks are in 1 gallon per seconds?
1 gallon per seconds equals 80,850 cubic foot per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cubic foot per weeks?
Multiply the gallon per seconds value by 80850. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per weeks back to gallon per seconds?
Use the reverse factor: 1 cubic foot per weeks equals 0.0000123686 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a cubic foot per weeks?
Cubic foot per Weeks (ft3/wk) is a unit of flow rate.
Is the gallon per seconds to cubic foot per weeks conversion exact?
Yes. Both gallon per seconds and cubic foot per weeks are defined by fixed standards rather than physical artifacts, so the factor of 80850 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.
