About Converting Cubic foot per Days to Cubic Millimeter per Days
Cubic foot per Days and Cubic Millimeter 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 millimeter per days = cubic foot per days × 28316846.592
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 millimeter per days equals 1.157407e-14 base units, so dividing one by the other gives the direct cubic foot per days-to-cubic millimeter per days factor of 28316846.592.
Simple example
1 ft3/d × 28316846.59 = 28,316,846.59 mm3/d
1 cubic foot per days = 28,316,846.59 cubic millimeter per days.
Real-world example
60 ft3/d × 28316846.59 = 1,699,010,796 mm3/d
60 cubic foot per days = 1,699,010,796 cubic millimeter per days.

Frequently asked questions
How many cubic millimeter per days are in 1 cubic foot per days?
1 cubic foot per days equals 28,316,846.59 cubic millimeter per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per days to cubic millimeter per days?
Multiply the cubic foot per days value by 28316846.59. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per days back to cubic foot per days?
Use the reverse factor: 1 cubic millimeter per days equals 3.531467e-8 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 millimeter per days?
Cubic Millimeter per Days (mm3/d) is a unit of flow rate.
Is the cubic foot per days to cubic millimeter per days conversion exact?
Yes. Both cubic foot per days and cubic millimeter per days are defined by fixed standards rather than physical artifacts, so the factor of 28316846.59 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.
