About Converting Cubic foot per Days to Cubic Kilometer per Weeks
Cubic foot per Days and Cubic Kilometer 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 kilometer per weeks = cubic foot per days × 1.982179e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per days equals 3.277413e-7 base units, and 1 cubic kilometer per weeks equals 1653.43915344 base units, so dividing one by the other gives the direct cubic foot per days-to-cubic kilometer per weeks factor of 1.982179e-10.
Simple example
1 ft3/d × 1.982179e-10 = 1.982179e-10 km3/wk
1 cubic foot per days = 1.982179e-10 cubic kilometer per weeks.
Real-world example
60 ft3/d × 1.982179e-10 = 1.189308e-8 km3/wk
60 cubic foot per days = 1.189308e-8 cubic kilometer per weeks.

Frequently asked questions
How many cubic kilometer per weeks are in 1 cubic foot per days?
1 cubic foot per days equals 1.982179e-10 cubic kilometer per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per days to cubic kilometer per weeks?
Multiply the cubic foot per days value by 1.982179e-10. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per weeks back to cubic foot per days?
Use the reverse factor: 1 cubic kilometer per weeks equals 5,044,952,389 cubic foot per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per days?
Cubic foot per Days (ft3/d) is a unit of flow rate.
What is a cubic kilometer per weeks?
Cubic Kilometer per Weeks (km3/wk) is a unit of flow rate.
Is the cubic foot per days to cubic kilometer per weeks conversion exact?
Yes. Both cubic foot per days and cubic kilometer per weeks are defined by fixed standards rather than physical artifacts, so the factor of 1.982179e-10 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.
