Displacement is a measure of volume, not area;

Volume = cubic inches

area = square inches

L x W x H = Volume

Make sure you measure all of the ports displacement. IE - Port walls

No that = cubic feet.

If you want the displacement in cubic feet it is divided by 1728. Other wise leave it alone and it is inches.
