About Converting Cubic inch per Seconds to Cubic foot per Weeks
Cubic inch 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 = cubic inch per seconds × 350
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per seconds equals 0.000016387064 base units, and 1 cubic foot per weeks equals 4.682018e-8 base units, so dividing one by the other gives the direct cubic inch per seconds-to-cubic foot per weeks factor of 350.
Simple example
1 in3/s × 350 = 350 ft3/wk
1 cubic inch per seconds = 350 cubic foot per weeks.
Real-world example
60 in3/s × 350 = 21,000 ft3/wk
60 cubic inch per seconds = 21,000 cubic foot per weeks.

Frequently asked questions
How many cubic foot per weeks are in 1 cubic inch per seconds?
1 cubic inch per seconds equals 350 cubic foot per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per seconds to cubic foot per weeks?
Multiply the cubic inch per seconds value by 350. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per weeks back to cubic inch per seconds?
Use the reverse factor: 1 cubic foot per weeks equals 0.0028571429 cubic inch per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/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 cubic inch per seconds to cubic foot per weeks conversion exact?
Yes. Both cubic inch per seconds and cubic foot per weeks are defined by fixed standards rather than physical artifacts, so the factor of 350 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.
