air flow conversion calculator air speed (distance moved per unit time) is usually expressed in linear feet per minute (lfm). multiply this by the air velocity of the duct cross-sectional area to determine the amount of air flowing through the duct per unit time. volumetric flow is usually measured in cubic feet per minute (cfm). the concept of wind speed can be used in air conditioning, heating, ventilation, etc.
