Converting cubic inches to cubic feet To convertcubic inches to cubic feet, divide by 178 To convertcubic feet to cubic inches, multiply by 178 Port Volume Calculation Theequation to calculate the volume ofa round port is: Radius x Radius x Pi x Net Depth. The net depth is the total depth ofthe port minus the thickness of the wood it is mounted in. For our example using a 4” port, 7.5” long, the equation would be: x x .1416 x (7.5-.075)= 84.85 cubic inches or 0.049
