About Converting Cubic foot per Days to Cubic foot per Minutes
Cubic foot per Days and Cubic foot per Minutes 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 minutes = cubic foot per days × 0.000694444444444
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 foot per minutes equals 0.0004719474432 base units, so dividing one by the other gives the direct cubic foot per days-to-cubic foot per minutes factor of 0.000694444444444.
Simple example
1 ft3/d × 0.0006944444444 = 0.0006944444 ft3/min
1 cubic foot per days = 0.0006944444 cubic foot per minutes.
Real-world example
60 ft3/d × 0.0006944444444 = 0.0416666667 ft3/min
60 cubic foot per days = 0.0416666667 cubic foot per minutes.

Frequently asked questions
How many cubic foot per minutes are in 1 cubic foot per days?
1 cubic foot per days equals 0.0006944444 cubic foot per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per days to cubic foot per minutes?
Multiply the cubic foot per days value by 0.0006944444444. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per minutes back to cubic foot per days?
Use the reverse factor: 1 cubic foot per minutes equals 1,440 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 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.
Is the cubic foot per days to cubic foot per minutes conversion exact?
Yes. Both cubic foot per days and cubic foot per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.0006944444444 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.
