measures the cargo carrying capacity of a ship, and is a universal, and straight-forward, method of calculating ships dues.

 , abbreviated as , represents the total internal volume of the whole vessel, including crew spaces, bridge, engine compartment, etc.

 , abbreviated as , is the volume of cargo the ship can carry, i.e., available volume for transporting freight or passengers.

 , abreviatted as , is a function of the volume of all ship's enclosed spaces, i.e., the ship's overall internal volume. Both and are estimated by measuring ship's volume and then applying a mathematical formula.


Weight

 : the actual total weight of the vessel, usually expressed in metric tons (m.t.). It is easily estimated by multiplying the volume, in cubic meters, of the hull below the waterline by the density of the water, in kilograms/cubic meter.

 : the actual weight of the vessel with nothing on board (crew, fuel, cargo, water, etc.).

 , abbreviated as , is the displacement at any loaded condition minus the weight. DWT serves to classify vessels by weight.
