Rectangular to round conversion.
Square duct to round duct calculator.
Step 5 select a size of square duct that has the same area.
To then convert that to volume you multiply the resulting area by the length.
The rectangular dimensions and the air flow volume are adapted to the equal friction loss.
Round use a slightly smaller diameter for less crimping or to finish the top with an added round collar lower.
