n: a mathematical means of approximating the small quantities of liquid and solid cargo and free water on board before a vessel is loaded and after its cargo is discharged, based on cargo compartment dimensions and vessel trim. It is used only when a wedge exists and when the liquid does not touch all bulkheads.

n pi: pre-calculated ships tables based on the wedge formula and displayed in much the same way as the ships innage/ullage tables. Used for small quantities when the liquid does not touch all bulkheads.
