About Converting Cubic Kilometer per Days to Cubic foot per Days
Cubic Kilometer per Days and Cubic foot 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 foot per days = cubic kilometer per days × 35314666721.5
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per days equals 11574.0740741 base units, and 1 cubic foot per days equals 3.277413e-7 base units, so dividing one by the other gives the direct cubic kilometer per days-to-cubic foot per days factor of 35314666721.5.
Simple example
1 km3/d × 35314666720 = 35,314,666,720 ft3/d
1 cubic kilometer per days = 35,314,666,720 cubic foot per days.
Real-world example
60 km3/d × 35314666720 = 2.11888e+12 ft3/d
60 cubic kilometer per days = 2.11888e+12 cubic foot per days.

Frequently asked questions
How many cubic foot per days are in 1 cubic kilometer per days?
1 cubic kilometer per days equals 35,314,666,720 cubic foot per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per days to cubic foot per days?
Multiply the cubic kilometer per days value by 35314666720. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per days back to cubic kilometer per days?
Use the reverse factor: 1 cubic foot per days equals 2.831685e-11 cubic kilometer per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per days?
Cubic Kilometer per Days (km3/d) is a unit of flow rate.
What is a cubic foot per days?
Cubic foot per Days (ft3/d) is a unit of flow rate.
Is the cubic kilometer per days to cubic foot per days conversion exact?
Yes. Both cubic kilometer per days and cubic foot per days are defined by fixed standards rather than physical artifacts, so the factor of 35314666720 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.
