About Converting Cubic foot per Minutes to Cubic Kilometer per Days
Cubic foot per Minutes and Cubic Kilometer 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. Cubic foot per Minutes is most often used for the standard unit for rating hvac airflow, compressed-air equipment output, and fan/blower performance.
Formula
cubic kilometer per days = cubic foot per minutes × 4.077626e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per minutes equals 0.0004719474432 base units, and 1 cubic kilometer per days equals 11574.0740741 base units, so dividing one by the other gives the direct cubic foot per minutes-to-cubic kilometer per days factor of 4.077626e-8.
Simple example
1 ft3/min × 4.077626e-8 = 4.077626e-8 km3/d
1 cubic foot per minutes = 4.077626e-8 cubic kilometer per days.
Real-world example
60 ft3/min × 4.077626e-8 = 0.0000024466 km3/d
60 cubic foot per minutes = 0.0000024466 cubic kilometer per days.

What is a cubic foot per minutes?
Cubic foot per Minutes (ft3/min) measures volumetric flow rate. One cubic foot of volume passing a point every minute. It is classified as a US customary flow-rate unit.
What is a cubic kilometer per days?
Cubic Kilometer per Days (km3/d) is a unit of flow rate.
Is the cubic foot per minutes to cubic kilometer per days conversion exact?

United States, and widely recognized internationally in HVAC and compressed-air equipment specifications
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.
