About Converting Cubic foot per Minutes to Cubic Meter per Seconds
Cubic foot per Minutes and Cubic Meter per Seconds 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 typically associated with united States, and widely recognized internationally in HVAC and compressed-air equipment specifications, while Cubic Meter per Seconds is typically associated with used internationally in hydrology and large-scale water-resource engineering.
Formula
cubic meter per seconds = cubic foot per minutes × 0.0004719474432
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 meter per seconds equals 1 base unit, so dividing one by the other gives the direct cubic foot per minutes-to-cubic meter per seconds factor of 0.0004719474432.
Simple example
1 ft3/min × 0.0004719474432 = 0.0004719474 m3/s
1 cubic foot per minutes = 0.0004719474 cubic meter per seconds.
Real-world example
60 ft3/min × 0.0004719474432 = 0.0283168466 m3/s
60 cubic foot per minutes = 0.0283168466 cubic meter per seconds.

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 meter per seconds?
Cubic Meter per Seconds (m3/s) measures volumetric flow rate. The SI coherent unit for volumetric flow rate — one cubic meter of volume passing a point every second. It is classified as a SI coherent derived unit.
Is the cubic foot per minutes to cubic meter per seconds conversion exact?
Yes. Both cubic foot per minutes and cubic meter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0004719474432 used above is exact to as many digits as you choose to display.

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.
