About Converting Cubic foot per Minutes to Cubic Millimeters per Millisecond
Cubic foot per Minutes and Cubic Millimeter per Millisecond 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 millimeters per millisecond = cubic foot per minutes × 471.9474432
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 millimeter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct cubic foot per minutes-to-cubic millimeter per millisecond factor of 471.9474432.
Simple example
1 ft3/min × 471.9474432 = 471.9474432 mm3/ms
1 cubic foot per minutes = 471.9474432 cubic millimeters per millisecond.
Real-world example
60 ft3/min × 471.9474432 = 28,316.84659 mm3/ms
60 cubic foot per minutes = 28,316.84659 cubic millimeters per millisecond.

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 millimeter per millisecond?
Cubic Millimeter per Millisecond (mm3/ms) is a unit of flow rate.
Is the cubic foot per minutes to cubic millimeter per millisecond conversion exact?
Yes. Both cubic foot per minutes and cubic millimeter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 471.9474432 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.
