About Converting Cubic foot per Weeks to Cubic inch per Days
Cubic foot per Weeks and Cubic inch per Days 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 inch per days = cubic foot per weeks × 246.857142857
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per weeks equals 4.682018e-8 base units, and 1 cubic inch per days equals 1.896651e-10 base units, so dividing one by the other gives the direct cubic foot per weeks-to-cubic inch per days factor of 246.857142857.
Simple example
1 ft3/wk × 246.8571429 = 246.8571429 in3/d
1 cubic foot per weeks = 246.8571429 cubic inch per days.
Real-world example
60 ft3/wk × 246.8571429 = 14,811.42857 in3/d
60 cubic foot per weeks = 14,811.42857 cubic inch per days.

What is a cubic foot per weeks?
Cubic foot per Weeks (ft3/wk) is a unit of flow rate.
What is a cubic inch per days?
Cubic inch per Days (in3/d) is a unit of flow rate.
Is the cubic foot per weeks to cubic inch per days conversion exact?
Yes. Both cubic foot per weeks and cubic inch per days are defined by fixed standards rather than physical artifacts, so the factor of 246.8571429 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.
