About Converting Cubic Millimeter per Seconds to Cubic foot per Days
Cubic Millimeter per Seconds 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 millimeter per seconds × 0.00305118720474
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per seconds equals 1e-9 base units, and 1 cubic foot per days equals 3.277413e-7 base units, so dividing one by the other gives the direct cubic millimeter per seconds-to-cubic foot per days factor of 0.00305118720474.
Simple example
1 mm3/s × 0.003051187205 = 0.0030511872 ft3/d
1 cubic millimeter per seconds = 0.0030511872 cubic foot per days.
Real-world example
60 mm3/s × 0.003051187205 = 0.1830712323 ft3/d
60 cubic millimeter per seconds = 0.1830712323 cubic foot per days.

Frequently asked questions
How many cubic foot per days are in 1 cubic millimeter per seconds?
1 cubic millimeter per seconds equals 0.0030511872 cubic foot per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per seconds to cubic foot per days?
Multiply the cubic millimeter per seconds value by 0.003051187205. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per days back to cubic millimeter per seconds?
Use the reverse factor: 1 cubic foot per days equals 327.74128 cubic millimeter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) 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 millimeter per seconds to cubic foot per days conversion exact?
Yes. Both cubic millimeter per seconds and cubic foot per days are defined by fixed standards rather than physical artifacts, so the factor of 0.003051187205 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.
