Converting a round port to a slot port. Calculate the area of the round port(s) being used, then use the square root function of your calculator to get the interior dimensions of an equivalent suare port. The length (or depth) of the slot port will be the same as that of the round port. To calculate area: ( Area is a two dimensional measurement ) Circle =3.14 x Radius x Radius Circle Port 4" 2" B U I L D I N G A N E N C L O S U R E 2" 4" Port 2 x 2 x 3.14=12.6 1" 12.6 x 1=12.6 Slot Port 12.
