About Converting Cubic foot per Minutes to Tablespoon per Seconds
Cubic foot per Minutes and Tablespoon 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 most often used for the standard unit for rating hvac airflow, compressed-air equipment output, and fan/blower performance.
Formula
tablespoon per seconds = cubic foot per minutes × 31.9168831169
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 tablespoon per seconds equals 0.0000147867647813 base units, so dividing one by the other gives the direct cubic foot per minutes-to-tablespoon per seconds factor of 31.9168831169.
Simple example
1 ft3/min × 31.91688312 = 31.91688312 tbsp/s
1 cubic foot per minutes = 31.91688312 tablespoon per seconds.
Real-world example
60 ft3/min × 31.91688312 = 1,915.012987 tbsp/s
60 cubic foot per minutes = 1,915.012987 tablespoon per seconds.

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.
