About Converting Cubic yard per Seconds to Gallon per Weeks
Cubic yard per Seconds and 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
gallon per weeks = cubic yard per seconds × 122153890.909
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per seconds equals 0.764554857984 base units, and 1 gallon per weeks equals 6.258948e-9 base units, so dividing one by the other gives the direct cubic yard per seconds-to-gallon per weeks factor of 122153890.909.
Simple example
1 yd3/s × 122153890.9 = 122,153,890.9 gal/wk
1 cubic yard per seconds = 122,153,890.9 gallon per weeks.
Real-world example
60 yd3/s × 122153890.9 = 7,329,233,455 gal/wk
60 cubic yard per seconds = 7,329,233,455 gallon per weeks.

Multiply the cubic yard per seconds value by 122153890.9. The converter above does this instantly to whatever precision you set.
How do I convert gallon per weeks back to cubic yard per seconds?
Use the reverse factor: 1 gallon per weeks equals 8.186395e-9 cubic yard per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per seconds?
Cubic yard per Seconds (yd3/s) is a unit of flow rate.
What is a gallon per weeks?
Gallon per Weeks (gal/wk) is a unit of flow rate.
Is the cubic yard per seconds to gallon per weeks conversion exact?
Yes. Both cubic yard per seconds and gallon per weeks are defined by fixed standards rather than physical artifacts, so the factor of 122153890.9 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.
