In our example, the height and width of the carrier are each 8 inches while the flow rate is 2700 linear feet per minute. The yield is 1200 cubic feet per minute. This script calculates a flow rate of cubic feet per minute from linear feet per minute. This 1st calculator automatically converts CFM to FPM for round ducts (you insert FPM, and the diameter of the duct, and you get CFMs). We will explain how to use the formula to calculate this as well. Register CFM depends on how many registers per room you have. For instance, if you have 3 registers in the same room, divide it by 3. So, 133.33/3 = 44.44 CFM. So per register will have 44.44 CFM in that room! Ideally, the average CFM per register is between 25 and 200.
