Airflow Value:-

Velocity Units:
-fl/min (LFM)
-m/s
-miles/hr (MPH)

Volume Airflow Units:
-ft3/min (CFM)
-m3/hr
-L/s

Dimension Units:
-in
-foot
-mm
-cm
-m

Air velocity (distance traveled per unit of time) is usually expressed in Linear Feet per Minute (LFM). By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time. Volume flow is usually measured in Cubic Feet per Minute (CFM).

Example Concept of Air Velocity can be used in air conditioning, heating and ventilating work.
